Use QFileInfo's file times in UTC for file timestamps

This is inherently faster than getting it in UTC from the underlying
native API stat call, then converting it to the Local Time Zone just to
compare them. The same goes for any use-case where you get a QDateTime
then the first thing you do is call t.to{Msec,Secs}SinceEpoch().
