> Abstract
> Daylight savings time adjustment may not be reported correctly by CEELOCT
> Content Europe will be implementing their DST changes this upcoming
> weekend and USA will be doing so the following weekend.
> ========================
> It was discovered that recent Language Environment APAR PI78252 is
> causing applications to receive an incorrect current time value after a
> change to the system time for Daylight Savings Time. The types of applications
> that are affected are Language Environment applications that make use of:
> Language Environment date/time callable services related to the local time,
> CEELOCT and CEEGMTO; High level language semantics that make use of
> these services, including the COBOL ACCEPT FROM TIME statement and the
> CURRENT-TIME function.
> PL/I application which use functions like date(), time(), datetime(), days(), 
> and
> secs() which use CEELOCT under the covers.
> 
> The circumventions immediately available are:
> to back off (smp/e RESTORE) the PTFs for PI78252, or to IPL the affected
> system after a Daylight Savings Time adjustment has been made.
> 
> APAR PI78252 has been marked PE. Final resolution will be shipped via OPEN
> APAR PI98400.
> Customers that are unable to IPL after the DST change and cannot back out
> the PTFs, can download the appropriate relief from the /fromibm/mvs
> directory on testcase.boulder.ibm.com
> LEETC.PI89400.HLE77B0 for z/OS 2.3
> LEETC.PI89400.HLE77A0 for z/OS 2.2
> LEETC.PI89400.HLE7790 for z/OS 2.1
