Subject: Enforce running with UTC
X-Git-Tag: 004~35
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=682b512d9b86eecb472ea3bcf89bfb02ee98082b;p=collecty.git

Enforce running with UTC

collecty records all data in UTC and writes them to the database
in UTC as well. When the system uses a different timezone the database
"corrects" the timestamps what we don't want here. Hence we force
resetting the timezone to UTC.
