But from what I recall from previous semiannual postings to this list: o IPL shouldn't be necessary. o Change the local time offset with an operator command. o The updated PARMLIB member will cover the next IPL. o If you have a Sysplex Timer, you can schedule the change in the Sysplex Timer. o Your Unix System Services TZ variables should be set to PST8PDT. There is no time change for UNIX. o Going forward is very safe. Going back is only a problem if you have applications so benighted as to keep critical timestamps in local time, and then to be upset when it regresses. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
