We have a platform with Embedded-Debian-Linux as OS which will be distributed worldwide. We have a Battery-Backed RTC which should be used as system time. We do not want to have any timezone or any info about localtimes.
But everytime we have ethernet conenction, the system time is changed to utc.
What we have tried till now
1) Removed localtime and zoneinfo file. -> No effect, time is still changing after pluging ethernet.
2) Setting localtime to /usr/share/zone/UTC -> Still no effect, time is automatically changed to utc.
My Question:
1) What is changing our time after pluging it into the ethernet?? We do not have any time-server!
2) Is there anyway to adjust the system, so that we do not rely on any timezone info. all we need is just to use Embedded-RTC as our timeinfo.
