Thanks in advance

Data fields:
Date1
Date2
Time1
Time2

Date1 & Date 2 defined as Date fields, Time1 & Time2 defined as Time
fields

Calculation Field

TimeDif =
(Date2-Date1) *24*60*60
+
Time2-Time1

TimeDIff field specified to give calculation result as Time

You can of course multiply out 24*60*60 and use the result as a single
multiplication factor.

If you are using 7 or better and just looking for number of hours
between the two, you can use the timestamp function to combine the dates
and times and do the heavy lifting:

(Timestamp ( date1 ; time1 ) - Timestamp ( date2 ; time2 ))/3600

result as a number

Re: Time intervel calculation

Opps, my bad:

(Timestamp ( date2 ; time2 ) - Timestamp ( date1 ; time1 ))/3600

result as number
