For now this accepts the UTC[+-]hhmm format (UTC has aliases GMT/Z and optional).
Additionally it accepts all zone abbreviations mentioned below in TZ_STR.
Note that currently this zone abbreviations are offset-based and used fixed
offset without automatically DST-switch (if CET used then no automatically CEST-switch).
In the future, it may be extended for named time zones (such as Europe/Paris)
present on the system, if a suitable tz library is present (pytz).

Parameters
----------
tz: symbolic timezone or offset (for now only TZA?([+-]hh:?mm?)? is supported,
as value are accepted:
int offset;
string in form like 'CET+0100' or 'UTC' or '-0400';
tuple (or list) in form (zone name, zone offset);
dt: datetime instance for offset computation (currently unused)
