‘id=3’ last time (12:51:00) + $interval (60 seconds)

How to toast , jam & marmalade

do you have a question ;) if so what is it ?

If I set it to sleep for 24 HOURS, will that cause any problems on my server, having this program sleeping for an entire day?

I want a user to fill out a form and then send them a response in 24 hours. I can't use my autoresponse service b/c the response is customized according to how they answer questions on the form.

TIA for any advice!
