# Display current time in UTC in the menu bar.
# Optionally display current time in one or more additional zones in the drop-down list.
# The display format HH:MM:SS will refresh every second when the file name ends with ".1s.sh", e.g. "worldclock.1s.sh".
# To refresh less frequently, e.g. every 30 seconds, rename the file "worldclock.30s.sh". In this case
# the format could be changed to remove seconds from the display by using `date -u +'UTC %H:%M %b %d'`.
