I read this question and I've a similar request but not identical. I need a programmable alarm clock with the following features:
- set the interval in minutes
- set the begin and end time
For example I want to setup an alarm that fires from 10:00 to 18:00 every 90 minutes. Nice to have (even not mandatory) to set on which days should run.
I tried the Gnome Clock Applet and Teatime but they do not fit my requirements.
