Introduction:
We have 4 lpars in sysplex mode.  When we started TLMS, the message CAT9012I was issued. What causes this message to be produced?
Instructions:
 The CPU in the VMF control record is used to track start/end time of TLMS. This information will then be used at startup to verify the date. If older than 24 hours, this might result in messages CAT9012I and CAT9013P
CAT9012I CA TLMS - DATE/TIME ON CPU cpuid MAY BE INVALID
Reason: TLMSTAGE: This message occurs only on multiple CPU systems when CA TLMS is activated. This message is issued if the current machine date/time is before the time CA TLMS last ended, or more than 24 hours after the last end time. The CPU ID indicated by cpuid may have a different date/time than the current system.
Action: None. This is an informative message.
However, all systems should have their TOD clocks synchronized so the time stamps in the VMF will be meaningful. * The CAT9012I and CAT9013P messages are really only informational. They indicate that TLMS detected that an excessive amount of time between the last shutdown, and the current TOD clock. Messages can be removed using "CMSG=CAT9013P,MSG=SUP" in TLMSIPO member from PPOPTN.
