Allan, Yabbut... Do I still have to pay $10K's to buy an external timer in order to get a fully automatic CST/DST time flip and to get my z14 to get in sync with our NTP servers that the rest of our company uses?

None of the major IBM subsystems depend on local time for logging and recovery (since at least the late 80's Almost universal, however is "application paranoia". The fear that there is something somewhere dependent on the local timestamp and *might* break something. This has led to persistent 1 hour outage once/year for the fall time change where the local timestamp can possibly overlap, in many cases. -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of EDWARD GOULD Sent: Tuesday, July 23, 2024 2:56 PM To: [email protected] Subject: Re: CTN's and auto DST changes [CAUTION: This Email is from outside the Organization.

Contact the suppliers. > Gil, We used to have an ancient version of CICS that did that. The issue was that it ran the ATMs and the online banking system. If it went down for more than X amount of time (I think it was 15 minutes or an hour?), we were fined by the fed 10K ($ ?). Everyone, including the management, did not want to touch it. We were stuck with this, yet we had to keep the OS current. How do you want to call IBM on an unsupported version of CICS?
