To get the number of days, divide the microsecond interval by 86,400,000,000 (a 64-bit number; divide by a million and then by 86,400 if you are more comfortable with that). The quotient is the number of whole days in excess of your hours, minutes and seconds. (You know how to remember about z division? quOtient in the Odd register; rEmainder in the Even register.)

It's strong enough to find the elapsed time for larger numbers than I intended. So much so, I thought I'd add a function to show the elapsed time since the beginning of my started task. The time is working wonderfully but when I cross the more than a day boundary I'd like to display the number of days since the start of the program. I wound up using the STCK-STCK difference in times since the start of the started task + 1972/01/01 add in base STCK time to get a STCK value again STCKCONV convert that to DATE=YYYYMMDD TIME=DEC ED make it character based sequence so I have 1972/01/03 23:15:06.238744 What I'd like is 2 days 23:15:06.238744 I can calculate the date difference by hand (in C based off of the character representation of the date) of course. Unless someone knows of a nifty method to get the elapsed number of days from the data that I have? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
