SET TIMEZONE doesn't rely on issuing a SET CLOCK command as the SETHOUR program does, so it is "exact" where as with the SETHOUR program the seconds may not even match the GMT time. I wish there was a PARMLIB option to say "use the sysplex timer for offset but apply this additional offset criteria". Having that would eliminate manual changes on all the LPARs that don't use the same local offset as STP. I wonder if there has ever been a requirement submitted for this.
