Hello,

Is mktime() dependent on PHP or the server's OS? I just read that
starting next year, the time switches for daylight saving time will be
"on the second Sunday of March and end the first Sunday of November"
instead of the current setup.

http://webexhibits.org/daylightsaving/b.html?y=3000

I am worried because my application deals a lot with Unix timestamps,
and I'm not sure how this change would affect everything.

I tested the new date for daylight saving on March 11, 2007 on Windows
XP and it was not correct - it is still reporting the first Sunday in
April as the date of the switch. I am not sure about Unix, as I have
not tested it. Additionally, I am using php 4.3.10, so if it is in fact
PHP version dependent, I'm not sure what I can do without upgrading.

Thanks for all your help.
