Re: UNIX and System time in z/OS
>I will work on all of these answers and see which one works for me. Some thoughts to consider: - Whatever is set in /etc/init.options is only relevant to any process started from /etc/rc (and some of these may even neglect those values, e.g. inetd does not propagate them to clinets logging in through telnet/rlogin). - /etc/profile only becomes active when a login shell is started. Is has no effect on UNIX programs started via JCL EXEC PGM=. - Parmlib member CEEPRMxx gives you the option to set environment variables for the LE environment, which would help all programs written in a high level language. It would not help (probably, I haven't tried) for Assembler programs doing BPX UNIX API calls. >At this time, the /etc and UNIX in general has not been customized. >So I am tackling this process one step at a time.

Re: UNIX and System time in z/OS
As always - more than one way to skin a cat. All excellent answers and now I must dig deeper and deeper into UNIX and the /etc folder. I knew about the /etc/profile. I did not know about the /etc/init.options. So many places so little time. And yes, it would be nice if IBM set it up with a single point of customization. I will work on all of these answers and see which one works for me. At this time, the /etc and UNIX in general has not been customized. So I am tackling this process one step at a time. Once I get the time sorted out, I think I can complete the customization without any issues.

Re: UNIX and System time in z/OS
Hi Lizette, You may want to code the following in your profile and never have to worry about time change -- unless of course, some smart (?) politician decides to push for another change to DST: TZ=EST5EDT export TZ=EST5EDT,M3.2.0,M11.1.0 Regards, Jasbir Chauhan -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Lizette Koehler Sent: Monday, December 29, 2008 9:29 AM To: IBM-MAIN@bama.ua.edu Subject: UNIX and System time in z/OS running z/OS V1.9 with JAVA in Unix I would like to know if there is a way to establish the JAVA in UNIX to always get the system date and time.

Better answer that IBM doesn't support: There should be a single point of maintenance, either in PARMLIB or in STP that controls the final default TZ for both Classic and Unix environments.

If you use a format like TZ=CST6CDT (for central time) or TZ=EST5EDT (eastern time), that should take care of having to change it in the spring and fall. You should have this specified in your /etc/init.options and also in /etc/profile.

Set TZ to EST5EDT. That should cause it to shift automatically.

I would like to know if there is a way to establish the JAVA in UNIX to

This may work:
