Marc Mutz 474bee61e4 QtNetwork: convert some QDateTime::currentDateTime() to currentDateTimeUtc() 
The latter is much faster as it doesn't have to deal with
time zones.

This change is safe, because the QDateTimes are only used for
comparison with other QDateTimes, which, from a quick glance around,
seem to be mostly, if not exclusively, in UTC. Comparsions work
across time zones, but the comparison between UTC date-times is
fastest.

Credits to Milian Wolff, from whose QtWS15 talk this advice is
taken.
