>I am looking for a function, or maybe some code to help me calculate time only, no dates. I would like to be able to store 2 different times like 8:45 and 9:03 and figure how much time went by, or say the time is 8:55, now add 10 minutes. Would I have to store these figues in a character field?

How about storing these values in a numeric field, the number representing the number of seconds since midnight to the time you want. You can write methods to convert them in and out of your times.

But I would just use DateTime, and simply ignore the date.
