A question just came up from my Information Security dept. about setting and synching the Mainframe clocks. We generally reset them whenever we have a full system shutdown and don't worry about it otherwise but they now want a procedure to regularly correct clock drift.
Please correct me if I'm wrong Hardware Clock - Set via HMC/SE to (In my case) GMT/UTC. TOD Clock - Set from Hardware clock at LPAR Activation time, not synched to hardware clock after then. SIMETR - Set from TOD clock by first LPAR referencing it. All other LPARs with same SIMETR will have same time reference. The only way to 'correct' GMT/UTC clock drift in a plex using SIMETR would be to Deactivate all LPARs (using the same reference) then Activate to get new TOD/Hardware reference. If using an ETR (9037) TOD clocks are continuously (FSVO continuous) synched to the ETR and a change to the ETR GMT/UTC setting will be propagated to all referencing LPARs without need for Deactivation/IPL. Thanks all.
