The fields can be in these forms:
- Single Number: 5
- List of Numbers: 0,15,30,45
- Range of Numbers: 1-5
- All: *
From memory here, not bothering to check Google at the moment, but can you not also mix a list and range?
0,8-17,22So that would send at midnight, and every hour 8-17 and then 22?
Yes, I'm pretty sure that that is correct.

I've been dealing with cron for... 22 years I guess, and it still irritates the hell out of me. Anyway, great work.

Just to point out, there are some other strings you can use also.
@yearly @weekly @dailyYou can also use
/0-30/5 * * * *Is every 5 minutes for the first 30 minutes.
I didn't know about the '/' That's really good to know.

I tacked it on in the advanced section at the end. This one I've seen used in real life. Never seen anyone use @monthly, for example. I know that it exists, but just have never seen it get used.

I do, for expiring old user sessions.

I was going to say that it's another handy reference to the time formatting for cron, but I normally just use the man page.
