I am not sure if you intended to send this to me or to the list. It went to the list so I am responding there. There are 2 types of items in SYSTEM CONFIG that are related but are semi-independant of each other. One is the timezone definition, where you would define that CST is so many hours west of GMT and CDT that is one hour more. Then you have the timezone boundry that gives the date/time that the time change occurs on. There are usually multiples of these for several years into the future. I don't have my manuals handy so I don't have the exact syntax of these statements. During your IPL, when you set the time, VM will look at the timezone boundrys to locate the most recent one that has past and will take the zone (CDT or CST) from that statement. Then it will take the difference from GMT from the proper timezone definition and will adjust the time you entered to be GMT, convert that to TOD clock format and put it in the TOD clock. If the TOD clock is already set, this is all automagic. Then when you do a QUERY TIME, the opposite calculation takes place so you see local time. The same thing happens when a virtual machine asks CP "what time is it?". If you are up when time change happens you just do a SET TIMEZONE CDT (or CST) and the only thing that changes is the correction from GMT to local the next time it is needed. I hope this helps. -- Rich Greenberg N6LRT Marietta, GA, USA richgr atsign panix.com + 1 770 321 6507 Eastern time zone. I speak for myself & my dogs only.
