# { name: timer_duration, type: select, select: "auto|streamripper|fpls", value: none, description: "Support for time ranges" }

#
# Provides an internal timer, to configure recording and playback times/intervals
# for stations. It accepts a natural language time string when registering a stream.
#
# Context menu > Add timer for station
#
# Programmed events are visible in "timer" under the "bookmarks" channel. Times
# are stored in the description field, and can thus be edited. However, after editing
# times manually, streamtuner2 must be restarted for any changes to take effect.
#
# Allowable time specifications are "Mon,Wed,Fri 18:00-20:00 record"
# or even "Any 7:00-12:00 play". The duration is only honored for
# recording via streamripper or fIcy/fPls currently.
