I have NO experience with this, but in the Image profile there in an option to use 'Logical partition time offset' in lieu of 'Standard time of day'. Would that help in managing multiple time zones?

I don't know if *you* consider that hardware or software, but I consider it "hardware". For the LPARs not running pacific time, it means taking the offset from software and changing CLOCKxx parmlib members twice a year and either IPLing or using "SET TIMEZONE". Prior to the existence of "SET TIMEZONE" (z/OS 1.7 and above) we either used RO *ALL,SET CLOCK = with getting the local time as close as we could to the GMT time or we used the SETHOUR program from CBT file 639 which did it for you and could get the local time set to the same second as the GMT time. It also updated the CLOCKxx member in parmlib.
