hi all,

my dispatch board shows work order objects of varying start times and duration. The duration can span across hours or days. The duration is also restricted to an 8 hour work day. So, the duration for a work order that spans 1.5 days is only 12 hours.

My question is...

Is it better to define the start and duration as two datetime fields or as one start datetime field and a duration time field?

Examples:
StartDateTime[12-10-05 09:00:00], EndDateTime[12-10-06 13:00:00]
- or -
StartDateTime[12-10-05 09:00:00], Duration[12:00:00]

thanks.
