Kevin,
The corresponding LE change on VM is in the EDCLOCI ASSEMBLE file.
>From the MAINT userid enter:
VMFSETUP ZVM LESFS
CUSTLE ZVM LESFS
select option 3, '"C" Locale Time Info'
I'm using the following for Eastern time in EDCLOCI ASSEMBLE, right or wrong.
EDCLOCI EDCLOCTZ TZDIFF=300,TNAME='EST', *
DSTSTM=3,DSTSTW=2,DSTSTD=0,STARTTM=7200,SHIFT=3600, *
DSTENM=11,DSTENW=1,DSTEND=0,ENDTM=7200,DSTNAME='EDT', *
UCTNAME='UTC'
After filing the changes, CUSTLE will assemble the file and build the new
modules.
VMFCOPY the new modules to the MAINT 19E, and save CMS. The LE shared segments
SCEE and SCEEX will have to be rebuild for the new modules.
Also, Language Environment APAR VM64117 / PTF UM31924 provides needed changes
to several C/C++ library functions.
Reference http://www.vm.ibm.com/service/DST2007.html for z/VM DST changes.
Interestingly, EDCLOCI ASSEMBLE is not mentioned on that web page.

On the z/OS side, we had some issues that we raised to IBM via an ETR. We ended
up adding a line to CEECOPT (LE Options) that specified the month, week and
time to change the clocks (US East Coast time was a default that we used
(probably without even realizing it). Certainly, the C localtime calls that we
do worked correctly with the added line to CEECOPT. An IBM APAR gave us some
issues as we currently have some of our systems at different PTF levels. Is
there a similar file to change under z/VM?

Yes, I have also date related problems:
In Madrid it's now 10'30 local time. But:
> date
mié mar 21 11:30:45 CET 2007
The DOW is correct and so is the date but the time is one hour in advance.
Don't know how to handle this.

Asunto: Re: Timezone change.
We patched all of our z/systems and when we rebooted some of them defaulted
back to UTC and the time was showing off. I reset them via yast to reflect
localtime and everything went well after IPL.
The following (DST weekend) I patched all my systems, made sure they were
reflecting localtime and now after IPL they are showing up on UTC time, but in
yast their are showing up as localtime.
Any ideas why some of my guests (across different lpars) boot in UTC even
though they show localtime and why some of my guests never had a problem with
this and always ipl into the correct hardware clock mode?
Anyone else experience this problem? Could it have something to do with VM and
how the guest is picking up its time on ipl?
Thanks.
