Writes a QTime for the given timestamp or DateTime object

The QTime will only carry the number of milliseconds since midnight.
This means you should probably only use this for times within the current
day.

If you pass a timestamp from any other day, it will write the number of
milliseconds that passed since that day's midnight. Note that reading
this number has no indication this is not the current day, so you're
likely going to lose the day information and may end up with wrong dates.

The QTime will be sent as the number of milliseconds since midnight,
without any awareness of timezone or DST properties. Thus, writing this
will assume it is relative to the current timezone. This means that the
time "14:10:34.5108" will be 14h after midnight, irrespective of its
actual timezone. The receiving side may not be aware of your local
timezone, so it can only assume its own local timezone as a base.

Make sure to use (i.e. convert via `setTimeZone()`) to the same timezone
on both sides or consider using the `writeQDateTime()` method instead,
which uses absolute time stamps and does not suffer from this.

You can also pass a Unix timestamp to this function, this will be assumed
to be relative to the local midnight timestamp. If you need more control
over your timezone, consider passing a `DateTime` object instead.
