RE: Convert and Duration

["Bob Cozzi" <cozzi@xxxxxxxxx>]

Use the ADDDUR and/or SUBDUR operation codes to calculate the duration.
First move the fields to real date/time fields (D or T), or to a timestamp
field (Z). Then perform the subtraction.

Subject: Convert and Duration

I've got a file with an 8 digit date (CCYYMMDD), a 4 digit time field (HHMM)
and a field that contains either a.m. or p.m. I can convert the time field
easily enough to be 24 hr time by adding 12 to hr field if pm and making
seconds 0.
 
Where I am stuck is how to get the duration between two sets of dates.times.
I know I probably need to move to date/time type fields but after that.
would like time duration to be in hrs/minutes.
 
Thanks
