I need to convert a time that is a string value to a time value only - i want to subtract 2 times to get the difference- it will not allow it because of it being a string?

Trying to accomplish this:

Currently the 15:10:00 and other time is a string.

15:10:00  -  15:01:00  =  9:00

Try this formula

mlmcc
Local StringVar strStart := {YourStartTimeSring};
Local StringVar strEnd := "{YourEndTimeSring};
local Timevar tmStart;
local Timevar tmEnd;
local NumberVar nbrSeconds;
local NumberVar nbrMinutes;
local NumberVar nbrHours;

tmStart := TimeValue(strStart);
tmEnd := TimeValue(strEnd);
nbrSeconds := DateDiff('s',DateTime(CUrrentDate,tmStart), DateTime(CurrentDate,tmEnd));
nbrHours := nbrSeconds\3600;
nbrSeconds := nbrSeconds mod 3600;
nbrMinutes := nbrSeconds\60;
nbrSeconds := nbrSeconds mod 60;

TimeValue(nbrHours,nbrMinutes,nbrSeconds);

Sorry i should have added that I have a date field that goes with the time - just separate
When I tried the formula above it comes up with all the times starting at 12:00. Do I need to add the date to the time?  When it tried before to do this formula it did not show properly

DTSToDateTime({FDC_Trips.atpsdate}+{FDC_Trips.atpstime})

The time shown on the left in the screen shot is the proper time. The time on the right side is when I use the formula above to convert to datetime value. No sure why it would be different?

I should have said to display the answer in 24hour format so that 0 hours shows as 0 hours rather than 12

What does the date field have?

If you need the date the function expects dates as 2011-01-01
