You should probably ask your question on the mvs-oe list: http://www.lsoft.com/scripts/wl.exe?SL1=MVS-OE&H=VM.MARIST.EDU
I don't know how to do this with a shell command, I think that you would have write a program. If your system has IBM Ported Tools perl, then that would work (google "perl date arithmetic"). I was thinking that another path might be to write a shell script in REXX and use the Unix syscalls. But the one you really need, mktime(), isn't listed in the "Using REXX with Unix System Services". Pity, that would have been quite doable.
