Actually, after our Operator's took us past Y2K, and back to 1900, too - I 
placed a "TODALLOW" package on the IBM VM Download page:
http://www.vm.ibm.com/download/packages/

No problems since!

---<snip>---
The TODALLOW EXEC is intended to be called from the PROFILE EXEC of 
AUTOLOG1. It is used to prevent AUTOLOG1 from continuing with standard 
AUTOLOG commands and other procedures if the current date and time are 
outside defined limits. 

TODALLOW compares the current date/time to the date/time of the most 
recent file on a specified, accessed CMS minidisk (e.g an OPERATOR system 
console log file - select one that is frequently updated). If the current 
date/time are different by more than a specified time range (e.g. 02:00 
hours) from that file, a message is issued to a specified userid 
(typically OPERATOR) and an reply is required from that user before the 
new date/time is accepted and standard procedures continue. This gives the 
Operator a chance to shutdown and change the TOD clock before application 
damage (tapes scratched, files deleted, etc.) can occur. 

The only pre-requisites are CMS Pipelines, and the IBM-distributed RXTOD 
MODULE (on MAINT's 193 disk). 

Updated 2000-10-13 to accept 'WNG' from OPERATOR, and reduce the time 
window between setting MSG/WNG/SMSG IUCV and waiting for a response, and 
better handle manual interrupts.

Re: Date Time Changes...






"I just updated the TOD at IPL time to be current with CDT"

If you set a correct timezone, you don't set date&time do you?  Unless to 
adjust the time drift of the z9 clock.

I did write some code to be included in AUTOLOG1 that will ask the 
operator to send an OK if the date differs more than 3 days with the last 
known date (which is saved daily by VMUTIL)
