View multiple timezones from anywhere in the world at once. Jump to any time in the past or future to see the time in any timezone.

You can even measure the time between events happening in different timezones. For example, if you know your flight from London to Dubai leaves at 19:00 London time and arrives the next day at 5:50 the next day Dubai time, Meridian will be able to tell you you'll be in the air for 6 hours 50 minutes.
