Red Alert for Time Change

Red Alert for Time Change

IBM has just released a new Red Alert relating to the time change, which is scheduled in the USA for November 5 and Europe this weekend:  2017.10.27 – Daylight savings time adjustment may not be reported correctly by Language Environment (LE) callable services if PTFS UI48771 / UI48801 / UI48802 are applied.

It appears that the problem is related to COBOL and PL/I programs accessing LE functions. If you have applied PTFs for APAR PI78252 (z/OS 2.1/2.2/2.3, closed 13Jul2017 ), you will need to back them off or IPL before the time change. Unfortunately, there is no indication in the APAR that there is a problem with it. APAR PI89400 was created to fix the problem, but it is OPEN and currently simply suggests a local fix (back off the PTFs or IPL the system).
