set time for action from program code

[jmosr]

I work at different times and i want to set an alarm by sending a SMS to my phone with the time to wake me up.
The SMS part is working, but i can't figure out how to set an alarm. Any ideas ?

Do you want to change the alarm-time at your clock or do you send sms' as "alarm-clock" ?
