Ive been racking my brain about this for the past 3 days, and have gone about through several ways I could accomplish the task at hand, but all of them have seeminly run into a brick wall of sorts.

The problem is this: I have output from a database ordered by the entry date field, there are three types of data 'open', 'hold', and 'closed'. What I am attempting to do is add up the total time of the 'open' data MINUS the entries that are on hold...so.. 
Date: Jan 1 2001 3:30PM | ID: 1 | Code: open
Date: Jan 1 2001 3:35PM | ID: 1 | Code: open
Date: Jan 1 2001 3:37PM | ID: 1 | Code: hold
Date: Jan 1 2001 3:46PM | ID: 1 | Code: hold
Date: Jan 1 2001 4:10PM | ID: 1 | Code: open
Date: Jan 1 2001 4:35PM | ID: 1 | Code: hold

Ive already written small subroutines to get my dates into unix epoch seconds, but I just cant find a decent way to calculate how long the 'ID' had an 'open' code and have been banging my head repeadatly at my desk with wrong numbers aplenty...I am pleading for help.
