The system time with RTC


The system boot up for the first time.

dmesg | grep rtc

I can get the RTC default time is setting system clock to 2000-01-01 01:00:19 UTC (946688419)

I also think the system time is 2000-01-01 …

But the system time is “2021-08-26 22:20:59”
(no network, so no ntp. just pure)

Do you know who config this setting? and where can I config it?


Sorry for the late response, is this still an issue to support? Thanks

Hi Kayccc,

Yes, that is still an issue.
We know RTC & NTP service can update it, but our customer still ask us the time
“2021-08-26 22:20:59” root cause.

Yours Sincerely,

Suppose it’s ubuntu 18.04 default time configure. Could you trace RTC driver to check if able found the configure file.
