Schedule a single non repeating task

[edsilber]

I'm trying to schedule a snapshot for 8:00 AM later this week. I've got the task created but when I go to the schedules I only get repeating cron results, I can't get it down to a single event. How can I make the equivalent of an at versus a cron.

And another possibly dumb question, Cron syntax seems to use months 1 through 12 but the web GUI seems to generate 0-11
