I have an AWS EC2 server running Amazon Linux (like rhel fedora) which does not know how to tell time, or is somehow not accounting for Daylight Savings Time. This makes all of my timestamps off by 1 hour.
[ec2-user@ip-xxx-xx-xx-xxx ~]$ date && date -u Thu Oct 24 17:19:56 EST 2019 Thu Oct 24 22:19:56 UTC 2019
The problem with that output is that (at the time of the command), the actual time in EST was
Again, UTC time is correct, I've set my
/etc/localtime link to
America/Detroit, but it still gloms onto
UTC-5 and does not adjust an hour for DST.
[ec2-user@ip-xxx-xx-xx-xxx ~]$ sudo hwclock --debug hwclock from util-linux 2.23.2 Using /dev interface to clock. Last drift adjustment done at 1571955488 seconds after 1969 Last calibration done at 1571955488 seconds after 1969 Hardware clock is on UTC time Assuming hardware clock is kept in UTC time. Waiting for clock tick... ...got clock tick Time read from Hardware Clock: 2019/10/24 22:23:43 Hw clock time : 2019/10/24 22:23:43 = 1571955823 seconds since 1969 Thu 24 Oct 2019 05:23:43 PM EST -0.689737 seconds
All of my tzdata is up-to-date. No updates pending on yum.
[ec2-user@ip-xxx-xx-xx-xxx ~]$ echo $TZ [ec2-user@ip-xxx-xx-xx-xxx ~]$ ls -l /etc/localtime lrwxrwxrwx 1 root root 23 Dec 8 2015 /etc/localtime -> /usr/share/zoneinfo/EST
I'm at a loss. Does anybody know what could be going on? Does Linux not adjust for DST?
