ClockSync synchronizes device system clock with atomic time from Internet via NTP (Network Time Protocol).
Useful if provider doesn't support NITZ, sends incorrect time or if your device/ROM has heavy clock drift.
There are 2 modes: automatic for root users and assisted manual mode for users without root (rootless mode).
Rootless mode features:
- automatic atomic time retrieval with configurable interval
- notification when offset exceeds user set threshold
- assisted manual synchronization with the hint what time/date to set
- precision between 1 and 30 seconds (because Android doesn't allow to set seconds)
- 1 second precision if your device resets seconds on Set (most Samsung and some HTC devices)
- Greenwich Time Signal assisted sync if device resets seconds
Root mode features:
- automatic sync with configurable interval
- accuracy is ~1-20ms depending on your connection and NTP server
- statistics (average drift per day, total time corrected)
Root is required because of Android security restrictions, vote for http://bit.ly/set_time_without_root if you want it to work without root, however Google has declined to fix it with the following comment:
"Hi, it is by design that applications can not change the time. There are many subtle aspects of security that can rely on the current time, such as certificate expiration, license management, etc. We do not want to allow third party applications to globally disrupt the system in this way." © some Google employee
- customizable NTP/SNTP server and timeout
- displays current date or time since last sync
- NTP server details dialog
- 3 color schemes (dark, light, default)
- 12-hour or 24-hour clock format
- time zone detection and adjustment based on geo location
- system time zone override with custom offset
- time zone management based on latest Olson tz database (zoneinfo)
- optional haptic feedback and sync notification
- clean and easy to use interface (tap screen values or use menu)
Don't have root? See http://bit.ly/phoneroot for the detailed instructions.
Don't want or can't root your device? You can still use ClockSync as your precise time source to adjust your watch or other clocks, or to verify how accurate your cell time is, or set time manually in rootless mode.
Move to SD is disabled because automatic synchronization (timers) will not work when app is moved, also app size is very small and since not all files are moved to SD in any case, it would not save you more than 50Kb.
If you get wrong time after synchronization, your phone time zone data is out of date, use http://bit.ly/tzupdate to fix it.
Issues, questions or suggestions? Please e-mail me, developers have no way to respond to Market comments.

1、get the NTP time quickly
Welcome to Time Calibrator!
Time Calibrator has been specifically designed to deliver accurate time information to people all around the globe. The app connects automatically to the atomic clock server in Switzerland to display the exact local time and date. Through quantum technology, the information travels at the speed of light from the NTP server and is communicated directly to AtomTime i-Atomic watches via light signals.
NTPSync is a simple NTP time synchronization app for Android.
To set system time to NTP time you need root access on your device, to just query the time you don't.
• Information can be found in in-app Help screen.
• If you have other problems please report them in the issue tracker on http://code.google.com/p/ntp-sync/issues
Source code/Bug reports/Translations
You can donate money to support the development in-app.
• Root access: To set system time
• Internet access: To query the NTP server
• Wakelock: To maintain a reliable network connection while querying NTP server
- your Android device needs to get a GPS fix for this app to work
- please try it outdoors, or close to a window
- Internet access is not required
- use menu to toggle between 12/24 hour clocks
- the overall accuracy depends on your GPS chip and how it sends its message to Android
- you can expect a typical accuracy of +/- 1 second
Different Android devices use different GPS chips, so:
- these chips all create slightly different NMEA messages
- we have tried to handle most cases
- please let us know if you have issues with your device
This application helps you keep the internal clock of your Android device accurate by synchronizing it with the GPS time signal.
ROOT access is required to actually set the time. The difference (in seconds) between your devices' time and the GPS time can be seen without root.

- Check and sync device's clock with GPS or NTP(Internet),
- Detect time zone by location,
- Time signal,
- Background time sync with NTP,
- Background passive time sync with GPS. Passive means the app uses GPS only when another app uses it,
- Very small memory footprint. In paid version even smaller - less 100Kb.
Automatic sync works only for rooted devices!
ATTENTION! IF YOU WANT THE APP TO SET TIME ZONES, IT'S REQUIRED TO INSTALL "SMART TIME SYNC TZ DATA" TOO. Just click on timezone field in the app and follow guide.
If the app doesn't work for you, please email me. I can't make the app better if you just leave a comment.
Please, rate the app if you like it. Thanks!
In free version background sync feature is time limited.
Mit dieser App ist es Möglich, Zeitinformationen von (NTP) Servern abzurufen. Es kann entweder der Standardserver oder ein beliebiger in den Settings eingestellt werden.
Nach Drücken auf den Refresh Button wird
- Die aktuelle Zeit
- Die Laufzeit (RoundTrimTime) ähnlich PING
- Die NTP Zeit (Sekunden seit 1.1.1900, 0:00)
- Die UNIX Zeit (Sekunden seit 1.1.1970, 0:00)
- Die Abweichung von der Systemzeit

Since Android 4.4 the /system partition can not be mounted rw for some devices (Note3 fore example) by this app. This has to be done manually before installing the custom gps.conf file before choosing to install. I'm sorry for the inconvenience!
This app does installs a customized gps.conf file for your GPS. It has several different profiles to choose from. We recommend to use the default Google profile but it is up to you. Appart from the profiles you can customize the one chosen.
Derek Gordon maintains a special NTP server pool for you. Dispite what everyone thinks, it is not necessarily the one closest to you which is the best. We consider Derek Gordon's server to be the best option to choose because it has the best data and is most frequently updated.
For more information about the NTP server check out the "About this app" section found under the settings of this app. Also, feel free to visit derekgordon.com for more in depth information.
Derek Gordon maintains a special aGPS almanac for devices using Qualcomm or similar chipsets. This xtra.bin data file is updated every 30 minutes and is located on a content delivery system maintained by the generous donations of ther userbase.
To maintain the server we need money. Donations through this app will be divided between Derek Gordon (Crypted on XDA) and Zatta (on XDA).
Each star costs 2 Euro and will reduce the waiting time before you can install the patch. 0 star users wait 20 seconds, 1 star users 10, 2 star users only 5 and 3 star users and Premium users can install immediately.
You can become a premium user for only 5 Euro. This is a discount of 1 euro compared to a three star user!
We choose this method to allow every one to use all features of this app and because we believe in XDA developers users. Please, don't leech!
Backup and restore
On the first run of this app a backup is made on your SD card. Don't remove it because a backup is only made during the first run (or at an update if you choose to remove it anyway) and no other backup is found on your SD card.
The patch this app provides is located on your /system partition so every time you do update your ROM the patch is overwritten and you will have to redo the patch.
Unless you are using a Cyanogenmod based ROM and your rom has addon.d support. In that case a script will be placed in the addon.d directory to preserve the patch. It can be disabled in the app's settings but is enabled by default.
On ASUS roms a typical file is present at /system/etc/gps, namely the gpsconfig.xml file. This app pathes that file as well, to be specific the PeriodicTimeOutSec parameter. Of course a backup is made of this file as well.
Special thanks to Sneakyghost for translating this app to German!
You can also synchronize time (only on rooted devices and BusyBox installed) - to protect your security app specially designed so you can see real command executed by super user (root).
If the app doesn't work for you, please get in touch with me. I can't make the app better if you just leave a comment.
Please, rate the app if you like it. Thanks!
The application obtains the current network time from any publicly available NTP servers, re-sync the time with the NTP server automatically every 10 minutes thereafter.
It also displays a countdown timer showing how long more until the next sync with the NTP servers and allows the user to trigger sync manually.
There are two mode for your choice: digital and analog clock style.
- Add, subtract, multiply and divide time components.
- Calculate time between two time values, e.g., 12:30 to 15:45 = 3h 15m.
- Convert calculated times by pressing the equals button again. The calculation will then cycle through all time units.
- See all your previous calculations in the history list.
- History entries can be used as memory recall.
- Commas with time units. Common in time reporting systems.
- Supports 12 and 24-hour clock.
- Easy to use. The app shows you which buttons and calculations that can be made.
- Jelly Bean design on all Android versions.
If you find a bug, please mail us instead of giving the app a low rating.
** Android 4.3 and higher currently is not tested in full. **
** HTC Users, due to system file protection, S-OFF is required (can works with S-ON for new phones) **
TimeZone Fixer is a small program which updates Android timezone files to the latest version (see "What's new" section). It is useful if the time zone changed in your area, or Daylight Saving Time has been abandoned or adopted.
Every 5 minutes the app will sync with NIST Internet Time Server (see http://www.time.gov/), to give you the most accurate time.
To verify that the sync works, the app shows the difference found between the device clock and the atomic time, on the bottom right corner.
This app uses advanced algorithms allowing much quicker access to the time data provided by the GPS circuit. What is incredible is that it can often show correct time and date while other apps still report 0 satellites in view! It has an automatic detection of the best available time and date raw info and uses dimmed text color as notification (warning) about unsettled outputs. Satellite Time Reader has a beautiful, retro-style user interface and will run on nearly any Google mobile/smart phone. Take it with you during you next holiday or while you are on a (sports) trip somewhere outdoors - you will love it!
Multilanguage support: English, German
This is the FREE version. The FULL version offers the following additional features and settings:
a) No advertising banner!
b) No permissions for internet access required!
c) Setting the system time (transferring the GPS based local time to your system time). THIS FEATURE ONLY WORKS ON SOME DEVICES WITH ROOT ACCESS AND MIGHT NOT WORK ON YOUR DEVICE! This is a limitation of the Android operating system – there is absolutely NO app on the market which can set the system time of a non-rooted device! And: It is not possible to synchronize system time and GPS based local time perfectly. There will always be some deviation (usually less than a second).
d) Keep screen on feature (avoid sleep mode while the app is active). Be aware that the GPS receiver draws a LOT of energy from your batteries!
e) Additional color schemes (white on blue, white on dark grey) - and the standard LCD scheme
1.) If the GPS time shows a wrong time, takes very long to receive, stops or does not appear at all, the GPS reception is not sufficient. This is not an issue related to the app!
2.) Using the GPS receiver consumes a lot of energy from your battery! It is not recommended to keep the app open for a longer time while it is on battery power only!
3.) If the local time is off by more than half an hour to the real local time then you have selected a wrong time zone in your device. Please correct the time zone FIRST and then the system / device time.
4.) Depending on your GPS hardware (!) this app offers instant (or at least ultra-quick) time info – much faster than traditional GPS monitor / tracking apps or maps based location / navigation apps! Note that this feature is known to work on Samsung Nexus S but cannot be guaranteed to work on your device. Reporting the status (fast or slow) on your device is highly appreciated (please send an email).
5.) You can tap on one of the three sections on your screen to get a short help about what is displayed in this section.
6.) Give it a try and test the free / lite version of this app. If you are satisfied after evaluation please consider buying the full / pro version (see details below).
I hope you have fun with this app! If so, please give a good rating and leave a comment. If you are not satisfied, please write a mail to firstname.lastname@example.org instead. Please describe what you don’t like plus give us a hint how it could be improved. You can also share this app with your best friend using the share button in the options menu - or use the Like button to find appformatics.com on Facebook.
NOTE: An offset of 15 seconds means your phone is set to GPS time (no leap-seconds).
NOTE: Setting the clock requires root access. See website for more info.
It can record your speed and location to a log file.

This is useful to send to the developer of an application in case it crashes or otherwise misbehaves.
*** It is only possible to read log files on Android version 4.1 (Jelly Bean) and later if your phone is rooted. ***
*** As of version 2.0, developers can embed SendLog into their own apps to add the ability to send logs. ***
You can choose any of the formats that logcat supports. The default and recommended format is "time".
It will add the output of "top" to the email. This shows the list of processes and the amount of CPU they are using.
You can create a home shortcut where you can specify the destination email, format and email client.
You can send to any app that supports attachments, such as Gmail, Dropbox, Skype, etc. Note that other applications such as Facebook, Twitter, etc will also be listed, but you should not choose any of these because they cannot handle attachments.
SendLog works with all Android versions and all phones and tablets. It will not truncate the log file. The log file is also stored as a text file on the root of the SD card, or the app folder if there's no SD card present.
It runs constantly in the background. When the Android system scans the Wi-Fi networks, Wifi Switcher will check to see if any of your preferred networks has a better signal strength than the one you're currently connected to. If it finds one significantly better then it will switch to it.
At home I have a Wi-Fi access point downstairs and another one upstairs. If I go upstairs I stay connected to the one downstairs but the signal is much weaker. This app will automatically switch you to the stronger Wi-Fi connection.
