# Finding the diffrence in time

I need to do a couple of things related to time but my math skills are not getting the job done.

Any help would be appreciated.

I have a perfect time (pt) and an actual time (at) I need to find the difference between those two in non negative numbers, and then have text that will tell me if the difference is late or early.

example 1

pt = 13:14:25

at = 13:14:26

desired result

Field 1 = at - pt = 1

Field 2 = at - pt = late

example 2

pt = 13:14:25

at = 13:13:24

desired result

field 1 = at - pt = 61

field 2 = at - pt = early

example 3

input

pt = 13:14:25

at = 13:14:25

desired result

field 1 = at - pt = 0

field 2 = at - pt = zero

Field 1 represents the difference between pt & at in seconds and needs to be positive so I can do a sum to get the total difference in time over multiple checkpoints.

Thanks Kevin

Field 1 (result is Number ) =

Abs ( pt - at )

Field 2 (result is Text ) =

Choose ( 1 + Sign ( pt - at ) ; "Late" ; "Zero" ; "Early")

Thanks comment that is perfect.

I figured there had to be something that would give an absolute number, I just couldn't think of how I could state it.

The sign I never would have got.
