Returns this DateTime value in the UTC time zone.
Returns this if it is already in UTC. Otherwise this method is equivalent to:
new DateTime.fromMicrosecondsSinceEpoch(microsecondsSinceEpoch, isUtc: true)
DateTime toUtc() { if (isUtc) return this; return new DateTime._withValue(_value, isUtc: true); }
