PROGRAM:
NAME
gworldclock - Displays time and date in specified time zones.
SYNOPSIS
gworldclock [ -f FILE ]
DESCRIPTION
gworldclock displays the time and date of specified time zones using a GTK+ interface. It
also allows the zones to be "rendezvoused" or "synchronised" to a time other than the
current time.
The time zones may be chosen from the list given in the GUI user interface. The zones
available are generated from the data in /usr/share/zoneinfo/zone.tab. The chosen set of
zones is stored in ${HOME}/.tzlist by default, but an alternate file may be specified at
the command line via -f. Alternatively this file may be created by hand in TZ format. The
zone list is kept in a format consistent with the shell script tzwatch, currently found in
twclock. The format consists of one TZ string per line, optionally followed by a human-
friendly string enclosed in inverted commas ("), providing a name for the zone.
OPTIONS
-f FILE
Read zone list from FILE instead of ${HOME}/.tzlist.
