Thanks, Mark! It's good to know about the e-mail client, never thought of it. Lotus Notes strikes again. But we'll be moving to Microsoft Exchange sometime this year, so Notes can't do that to me after that. Instead, Exchange will undoubtedly do all sort of new, unspeakable things to incoming and outgoing e-mail! :-( Life goes on...

Re: Determining Daylight Savings Time Status
Sidebar: The way that was posted makes it appear that I wrote both paragraphs. Actually, I only wrote the first sentence questioning whether the date had changed again. A subsequent poster appended the "snarkiness" paragraph, but that identity was lopped off in the way David's reply was posted. I'm certain that David never intentionally meant to post anything misleading; no problem there. Nonetheless, in this economy, I feel it important to be very sure that anything politically related, with my name and employer's name on it, is in fact what I wrote.

It wasn't clear to me that you wanted a general-user solution, or an algorithm that would project years ahead, or simply a utility to be run from MAINT.

Re: Determining Daylight Savings Time Status
Chip, The SYSTEM CONFIG supplied with z/VM 5.4.0 didn't go very far into the future. Maybe the VM Lab knows if some future congressionally-mandated timezone changes that we don't know about? :-) The distributed SYSTEM CONFIG for 5.4.0 contained only these statements related to timezone: -- Timezone_boundary on 2007-03-11 at 02:00:00 to EDT Timezone_boundary on 2007-11-04 at 02:00:00 to EST Timezone_boundary on 2008-03-09 at 02:00:00 to EDT Timezone_boundary on 2008-11-02 at 02:00:00 to EST Timezone_boundary on 2009-03-08 at 02:00:00 to EDT Timezone_boundary on 2009-11-01 at 02:00:00 to EST Timezone_boundary on 2010-03-14 at 02:00:00 to EDT Timezone_boundary on 2010-11-07 at 02:00:00 to EST Timezone_boundary on 2011-03-13 at 02:00:00 to EDT Timezone_boundary on 2011-11-06 at 02:00:00 to EST -- Using the SYSTEM CONFIG as a single-source-data is a good idea. But it depends on the security access of the virtual machines running Michael Coffin's application. I don't tend to give R/O access to MAINT's CFn R/O for to general users.
