Scheduled download by transmission during nightly hours? (downloading just at a specified period of a day)

The Speed Limit in Transmission throttles the upload/download speeds during the time set. What you want to do is set the upload/download speed values to 0 and implement that starting at 0800 and end at 0200. That should deactivate all uploads/downloads starting at 8am until 2am the following day.

I was going to use the above scheduled throttling, but thought of something additional and that is to just use the cron daemon via a start and stop: (e.g. Add the following to cron jobs via crontab -e)

 * 2 * * *  sudo service transmission-daemon start
 * 8 * * *  sudo service transmission-daemon stop

for you 2am-8am schedule. Perhaps even start it a little (5 minutes?) earlier/later?

The only problem I see from this though, is that the service won't be running during the day, when you want to add new torrents. So you'd have to start/stop manually whenever you are adding torrents (per "session")

Depending on your habits, this may/may not be convenient...
