You might want to have a look at the time-recurrence package: http://hackage.haskell.org/package/time-recurrence

For your simple cases you would do something like:

Each second:

starting (UTCTime ...) $ recur secondly

Each minute:

starting (UTCTime ...) $ recur minutely

Ouch. Look up "minutely" (my-NEWT-ly) in an English dictionary. Look up "secondly" while you're there.

You can blame RFC 5545 for that one. In section 3.3.10. our frequencies are: freq = "SECONDLY" / "MINUTELY" / "HOURLY" / "DAILY" / "WEEKLY" / "MONTHLY" / "YEARLY" Antoine
