Specifying the Listen-by date
If this option is on then a listen-by date is set for protected sounds.
When the applet runs
the current date is compared against the listen-by date and if the listen-by date has past
then the track isn't played and the "expired" message is displayed.
When specifying a date, SoundSafe accepts the day but not
the time of day. SoundSafe assumes the view-by time of day is the end of the listen-by day.
(Actually 1 minute to midnight on that day).
