RPI 4 Chrony Time Sync Question
Posted: Thu Jul 23, 2020 2:28 am
Hi,
I got an rpi 4 a couple days ago and installed centos 8 on it. It has chrony installed and every time I reboot it I see chrony resync time with NTP for huge gap, as below:
And every time it starts from Jun 22, 2018, 07:11:53. Does chrony read some initial timestamp from somewhere? Can it also be synced?
I understand if we shutdown rpi for a while then there will be a gap. but how come it always load the 2018 date?
Thanks!
