public void add_tz (Timezone zone)
Adds a copy of zone to this and emits an
timezone_added signal.
The this will use the TZID string returned by get_tzid as the lookup key,
which can be passed to get_tz to obtain zone again.
If the this already has an Timezone with the same TZID string as zone
, the this will remain unchanged to avoid invalidating any Timezone
pointers which may have already been returned through get_tz.
