We run all LPARs on UTC with local time managed by STP. However, the LPAR profile definition screen on HMC includes this:
Clock Type Assignment _ Standard time of day _ Logical partition time offset I believe that this option allows an LPAR to run with a (presumably geographic) offset different from other LPARs on the same CEC. I thought that the option was intended specifically to allow shops to run LPARs in support of various business applications around the world. I have no actual experience here. ;-( . .
