An addition to the job stream Frank posted; setting the TZ variable is also increasingly important. On our systems, our system-wide UDC XEQ's tz.pub.sys which is a command file containing simply; setvar tz "EST5EST" So I added to Frank's job an ECHO command that overwrites the tz.pub.sys file with the appropriate timezone. The end of the timezone job on our system now reads: !if hpday = 1 and hpmonth = 10 and hpdate > 24 then ! SETCLOCK TIMEZONE = W5:00 ! ECHO SETVAR TZ "EST5EST" > TZ.PUB.SYS ! TELLOP ********************************************* ! TELLOP Changing the system clock to STANDARD TIME. ! TELLOP The clock will S L O W D O W N until ! TELLOP we have fallen back one hour. ! TELLOP ********************************************* !elseif hpday = 1 and hpmonth = 4 and hpdate < 8 then ! SETCLOCK TIMEZONE = W4:00 ! ECHO SETVAR TZ "EST4EDT" > TZ.PUB.SYS ! TELLOP ********************************************* ! TELLOP Changing the system clock to DAYLIGHT TIME. ! TELLOP The clock jumped ahead one hour. ! TELLOP ********************************************* !endif So now, our clocks will be set correctly, and so will our TZ vars. :-) -Chris Bartram
