This mirrors the behaviour of the Alertmanager UI, which converts the
inputed string into UTC. This is better because otherwise you get mixed
timezones in the string representations when you query the
/api/v2/silences endpoint, for instance. It is also more "correct"
because Alertmanager uses UTC for presenting and updating dates, and so
amtool should do the same.
