The OP's "TOD" clock is set to local time. If the TOD clock is reset, the XCF *WILL* fail the IPL if the IPL time is earlier than the timestamp in the XCF couple dataset.

I agree all of the statements below, once the XCF couple datasets have the proper (GMT) timestamp. <snip> >DASD XCF is unaffected by the SET TIMEZONE or SET CLOCK commands. It uses the TOD clock internally (aka "GMT time"). DB2 also uses this clock. >CICS is a bit trickier because you must first issue the T CLOCK= or T TIMEZONE=, then for each CICS region, issue the command: CEMT PER RESET. >We do this using the MODIFY command to each CICS region. We have the z/OS consoles setup as CICS terminals so that we can do this. If all your CICS >regions start with the same "prefix", then your modify can looks something like: <F CICS*,CEMT PER RESET. >z/OS will issue a MODIFY command against every executing address space which begins with CICS for you. Handy if you have a decent naming >convention. </snip> BTW, don't forget to update the TZ environment variable in all of the myriad locations it appears in. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
