..."system may come up in GMT."
No, not "may" -- it absolutely WILL come up in GMT.
:blush on
Two weeks ago it took about 2 minutes to realize what *I* had done .. once
I stopped blaming the operators.
:blush off
Now. about future timezone dates... see the EXEC below. It produces a set
of statements good through the year 2041, and is easily changed if the US
Congress decides to create more mini-Y2K's before I am elected U.S. Grande
Pooh-Bah. Once so elected I will issue a Grande Pooh-Bah Declaration that
if it is wise to save daylight in the summer, it's even wiser to save it
in winter - so we'll stay on Daylight Savings Time which will henceforth
be known as Sir Mike Standard Time. So there!
Why do we save daylight in the summer time when there is so much of it?
Does Congress plan to spend it in winter? Obviously, that does NOT work.
In winter it's still dark when I get up to go to work in the morning and
before I go to home in the afternoon. Time for... Sir Mike Standard
Time! We have the technology. ;-)

Re: TIMEZONE
Don't forget to retain the record for the current period if you plan to
IPL before 3/11, otherwise you system may come up in GMT.
