|Summary||0000132: [Cloud/AWS]AMI wrongly assumes RTC as LOCALTIME|
|Description||Official AMI assumes syetem real-time-clock as LOCALTIME,|
but it is incorrect because EC2 supplies their RTC clock as UTC.
> Update the /etc/sysconfig/clock file with the new time zone.
> Do not change the UTC=true entry to another value.
> This entry is for the hardware clock,
> and does not need to be adjusted
> when you're setting a different time zone on your instance.
It may cause inaccurate time settings, espacially time zone is set OTHER THAN UTC.
Please consider changing default RTC setting, to UTC.
|Steps To Reproduce||[ec2-user@ip-172-31-44-137 ~]$ timedatectl status|
Local time: Wed 2021-10-13 09:46:11 UTC
Universal time: Wed 2021-10-13 09:46:11 UTC
RTC time: Wed 2021-10-13 09:46:11
Time zone: UTC (UTC, +0000)
System clock synchronized: yes
NTP service: active
RTC in local TZ: yes <------ INCORRECT FOR AWS
Warning: The system is configured to read the RTC time in the local time zone.
This mode cannot be fully supported. It will create various problems
with time zone changes and daylight saving time adjustments. The RTC
time is never updated, it relies on external facilities to maintain it.
If at all possible, use RTC in UTC by calling
'timedatectl set-local-rtc 0'.
