    Posted: 16 Jan 2015 at 4:41am
I have the following formula defined that calculates the date difference in days and excludes weekends:
 
Local DateTimeVar d1 := (DateTimeValue ({EpisodeTests.DateAuth},{EpisodeTests.TimeAuth} ));
Local DateTimeVar d2 := (DateTimeValue ({Tracking.TrackDate},{Tracking.TrackTime} ));
DateDiff ("d", d1, d2) - DateDiff ("ww", d1, d2, crSaturday) - DateDiff ("ww", d1, d2, crSunday)
 
I need for the formula to include the time and the output shoud be in hours. I also need to exclude weekends.

well, if the above works for days, I would think that you just use "h" or "hour" instead of "d". Not sure about the weekend stuff, maybe it needs to multiplied by 24.

it's an idea to start with

Ok. Thank you. I had tried with seconds. However, I am still puzzled about the weekend part.

if none of your start and end points can be on a saturday or a sunday I would guess that you can use lockewelle's suggestion of the hour ("h") difference and then multiple parts 2 and 3 of the formula by 24
This is a guess so test it out thoroughly though.
 
DateDiff ("h", d1, d2) - (DateDiff ("ww", d1, d2, crSaturday)*24) - (DateDiff ("ww", d1, d2, crSunday)*24)
