Subject: Time without Date

Is there any class or lib to deal with Times without Date?  (Eg "3:30
PM" - but I don't want it associated with a date.)

Ideally, I'd like to:
* Have clock arithmetic (1 AM minus 90 minutes is 11:30 PM)
* Convert from DateTime to dateless times (and, by adding a date, back)
* Store it with ActiveRecord

Any ideas?
