How can I run rules at a scheduled time?

I was hoping to run certain rules only at certain times of the day (mostly scripted stuff that launches other applications) to reduce the impact on my system when I am using it. Is there a way for me to tell Hazel to run a rule only during a certain time interval (between 11pm and 7am)?

Thanks!

As far as I know it's possible but definitely not straightforward.

You would need to set up a rule which triggers when a certain file is present. And then set up a crontab or recurring event in iCal, which would run an Applescript that creates this file.

Rule in Hazel:
For folder A
→ process if file F is present
→ your own rules

Event in iCal:
Repeat every day at 11 PM & alert run script → Applescript described below

Applescript:
Create (or copy) file F in folder A.

You would need another event at 7 AM that would run a script which deletes file F.

Note that 3.0 (due out soon...hopefully) will have support for this.

Oh wow, I didn't notice this option before. Well done!
