I have the same issue as
The /var/log/letsencrypt.log is showing the universal time and not the local time
last entry on letsencrypt.log
2018-02-17 14:07:02,862:DEBUG:certbot.renewal:no renewal failures
timestamp on file
/var/log/letsencrypt# ls -l letsencrypt.log
-rw-r--r-- 1 root root 234654 Feb 17 15:07 letsencrypt.log
Sat Feb 17 15:08:01 CET 2018
root@nondualvm:/var/log/letsencrypt# dpkg-reconfigure tzdata
Current default time zone: 'Europe/Amsterdam'
Local time is now: Sat Feb 17 20:24:48 CET 2018.
Universal Time is now: Sat Feb 17 19:24:48 UTC 2018.
Ive done all the reconfiguration, restart daemon etc none of this works. On this other topic there were no reactions. Do we have a bug here? can someone from letsencrypt take a look or maybe someone come with a better idea?
