Time anomoly?

[Hooker, Don - OIT]

We would be interested in hearing comments on this.   Before we IPLed on 10/30 for the timezone change (I usually do the SET TIMEZONE command but there was also a VM/Secure upgrade happening), we regenerated CP at 14:20 EDT.  At 14:46 EDT we IPLed our (z/VM 3.1) system.  The timezone definitions in SYSTEM CONFIG took place and we were back one hour, but it looks like we generated CP *after* we ipled and shows it generated EST rather than EDT (see below).  Is this to be expected?  Any comments?   q cplevel                                               z/VM Version 3 Release 1.0, service level 0401 (32-bit) Generated at 10/30/05 14:20:29 EST                      IPL at 10/30/05 13:46:04 EST                            Ready; T=0.01/0.01 17:12:59                             q timezone                                              Zone  Direction   Offset   Status                       UTC     ----     00.00.00  Inactive                     GMT     ----     00.00.00  Inactive                     EDT     West     04.00.00  Inactive                     EST     West     05.00.00  Active                       Ready; T=0.01/0.01 17:13:04                               - Don
