Time My Sleep

Each night I shutdown my MythTV server, and most nights something is still recording. That used to mean I had to set up a timed command - taking minutes each night.
I decided to speed up this daily job so I wrote Time My Sleep for me - and maybe it can help you too.

In the settings you can set up your server's IP address, the username & password, and the sleep command you want to run (something like 'echo "sudo /usr/sbin/pm-suspend" | at {time}', or any command that takes a time). Adding ";atq" on the end displays confirmation that the command has been set.
When you run the app you get to pick a time and when you hit the "Sleep" button, the command will have "{time}" substituted for the time you've picked.

This is a free app & it works for me. Your mileage may vary.
