# Provides an internal timer, to configure recording and playback times/intervals

# for stations. It accepts a natural language time string when registering a stream.

#
# 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.
