Hi, I have to calculate differences between date/time fields. The first date field is formatted as dd-mmm-yyyy hh:mm, but the other is in 2 fields, one with the date as dd_mmm_yyyy, the other as time hh:mm. I need syntax to concatinate these fields to a single field in the same format as the first date field, so I can get a difference in date/time between the two.

Thanks for any assistance here! Jeff
