Time Drift on BGS5T | Telit Cinterion IoT Developer Community
February 7, 2017 - 1:38pm, 1522 views
Hello
The Terminal BGS5T's system clock has a huge timedrift.
In order to prove it, I have been sending its timestamp to a server.
I made sure that my server was always sharp correct and in UTC.
I then calculated the difference between the server's timestamp and the module's timestamp
Conclusion: after 12h, all my 15 machines had a drift of around 400 secs!
Anyone with the same problems? Ideas to overcome this problem?
Gemalto, get a grip and start producing something good!
Hello,
There was a similar case for EHS5 on this forum: https://iot-developer.thalesgroup.com/threads/ehs5-rtc-systemcurrenttime... Please see.
There was a problem with System.currentTimeMillis() method where the frequent calling of this method was causing the RTC drifting. The workaround was to use the Timer and TimerTask instead. This was already fixed but not yet provided to the official release.
Best regards,
