I'm not quite sure why there's no timezone mentioned in my outputs. I've tried various settings (e.g. LANG=de_DE vs LANG=C), but there's never any timezone indicator in the outputs. But this seems to be an issue on my system.
Nevertheless, for the sake of argument, let's assume there's a timezone indicator in the output. As you can see from your outputs, you'll never get the expiration time of **02:00:00 PM CEST** / **14:00:00**, which would be the correct time representation in the case of TZ=Europe/Berlin. And as you can see in my last patch, the variable TZ is being cleared / unset. Since the check uses "%c" in strftime, the user can still choose his preferred TZ-settings. At last, I have found a more verbose example: ## current behavior ```shell TZ=UTC ./check_http -v -p443 -H github.com -C 7,3 --sni OK - Certificate 'github.com' will expire on Tue Apr 12 12:00:00 2016. ``` ```shell TZ=PST8PDT ./check_http -v -p443 -H github.com -C 7,3 --sni OK - Certificate 'github.com' will expire on Tue Apr 12 13:00:00 2016. ``` ## new behavior ```shell TZ=PST8PDT ./check_http -v -p443 -H github.com -C 7,3 --sni OK - Certificate 'github.com' will expire on Tue Apr 12 05:00:00 2016. ``` Since PST8PDT is UTC-8, the second output would be correct. -- Reply to this email on GitHub: https://github.com/monitoring-plugins/monitoring-plugins/pull/1337#issuecomment-95497698
