A “timegenerator” is something that describe _when_ you want to do something.
There are 3 kinds of timegenerators in larigira:
With single, you just set a single time the event should happen.
Sometimes you have something happening very regularly. For example you might want a jingle every 30minutes, or a specific show every friday at 8PM.
Sometimes your specification is very complex.
For example, you might want a specific message to be sent at 10:00, 13:00, 15:00 and 18:00, but only during working days. That would be hard to do with a single frequency event, so you could use a cron
0 10,13,15,18 * * 1-5
I know, that’s very difficult, but is still a possibility you have. If you want to learn how to write crons, check this helpful site.
