Mayelana nalolu hlelo lokusebenza

Uhlelo lokusebenza lwe- "E-CzasPL Clock" luyimpendulo esidingweni sokuvumelanisa isikhathi sohlelo samadivayisi eselula, lapho kunesidingo sokwenza ngokuhambisana nomthetho (ngokuphathelene nesikhathi), ngokuhambisana nezindinganiso ezivamile zekhwalithi kanye / noma ukuphepha, kanye nalapho kunesidingo sokuqinisekisa ukufana kwesikhathi esisetshenziswa umsebenzisi ngesikhathi esisemthethweni ePoland. Isicelo sivumela ukufinyelela okulula kokuvumelanisa isikhathi sesistimu yedivayisi nesikhathi esisemthethweni endaweni yeRiphabhulikhi yasePoland, noma sivumela ukunquma umehluko phakathi kwesikhathi sesistimu nesikhathi esisemthethweni, kucatshangelwa ukubambezeleka kwesixhumanisi (i-asymmetry yokudlulisela ) kumakhasimende ngamanye noma abamele imboni abasebenzisa amasistimu okusebenza asetshenziswa kakhulu emisebenzini lapho isikhathi sidlala indima ebalulekile (isb. Ukulawulwa kwenqubo yezimboni, abasebenzisi bezinkundla zokuthengwa kwempahla zomphakathi nge-elekthronikhi kanye nalabo abasingatha izinqubo ezihlukahlukene zokuncintisana).
Amathuba okuthola iwashi / isibonisi sesikhathi esisemthethweni ngendlela esheshayo nelula, okuthi, ngokwesibonelo, ibekwe kunoma iyiphi indawo yomphakathi. Uhlelo lokusebenza lunikezelwe kubasebenzisi aba:
• abanawo amaseva e-NTP;
• azidingi ukunemba okuphezulu kakhulu nokuthembeka ethuluzini lokuvumelanisa noma lokuqapha ukuphambana kwesikhathi sazo nesikhathi esisemthethweni;
• bakhombise isidingo sokusebenzisa umthombo wesikhathi onokwethenjelwa emishinini yabo ye-elekthronikhi (ephathwayo noma emile).
Ukuze usebenzise isevisi, umsebenzisi ufunda incazelo yohlelo, alande inguqulo efanele yohlelo futhi ayifake kudivayisi yakhe. Ngemuva kwalokho, ngenxa yokuqaliswa kwesoftware yenguqulo eyenziwe lula ye-NTP protocol - sNTP, ukwenziwa kusebenze ngakunye kwenketho efanele kukuvumela ukuthi uvumelanise isikhathi sohlelo nesikhathi esisemthethweni (uma uhlelo lokusebenza lomsebenzisi luvumela isenzo esinjalo), sibonisa isikhulu esivumelanisiwe. iwashi lesikhathi kuhlelo lokusebenza (ngaphandle kokushintsha isikhathi sohlelo), noma ukuqapha isikhathi sohlelo ngokumelene nesikhathi esisemthethweni ngesinyathelo esishiwo. Ukunemba kokuvumelanisa kusesimweni esibi kakhulu okweshumi kwesekhondi, kuma-milliseconds awodwa angcono kakhulu - kuye ngamakhono obuchwepheshe oxhumo lwe-inthanethi.
