We have a bunch of users here that work "Flexible" hours, full time but not always 8 hours in a row.  We need a sort of clock in clock out application.  In addition we would like to be able to track our OT for our non excempt employees.  All of this will eventually go back to which opportunity or account the exempt folks are working on so I figured SFDC was the right place.

Any suggestions for applications?  Anyone doing this themselves?

Thanks in advance for any suggestions.
