It returns a double value.. Any idea how the value is calculated ? I guess, this is in micro-seconds. Please clarify...

Hello,

Maybe this will help. . .

All references to time of day use the time-of-day (TOD) clock, a 64-bit binary counter. In the basic form, the TOD clock is incremented by adding a one in bit position 51 every microsecond.

If you'd like more detail, search the IBM documentation library for a manual called "Principles of Operations". No assembler programmer should be without one icon_smile.gif

Hi Suresh,

You will be able to find some material at
http://publibz.boulder.ibm.com/bookmgr_OS390/libraryserver/zosv1r7/
and
http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/download/A2278324.pdf%3fDT=20060213202835%26XKS=dz9zbk05

If those links won't work for you, search for +DZ9ZBK05 in Yahoo (it didn't work in Google).
