http://www.timeanddate.com/time/dst2009.html comes close, though it uses country names (+ locations, if necessary) rather than time zone names.

Thanks to all a lot for your answer(s).

I have a php script that takes the compiled timzone file and produces a report you might find useful. I have not published it yet, it was a project from long ago that I lost the need for so the page has not been kept up to date, but the program there works and may meet your need. http://timezones.foskie.com For example, if I give it the 2008b timezone file for new york and ask for 1991 to 2037, I get a table with: Entry for timezone file New_York (1267 bytes) For 1991 through 2037 ==================================== The second after is ==================================== Apr 07, 1991 02:59:59 EDT 03:00 EDT Oct 27, 1991 01:59:59 EDT 01:00 EST Apr 05, 1992 01:59:59 EST 03:00 EDT . . . Nov 01, 2037 01:59:59 EDT 01:00 EST The first line has an error, everything after that is correct. The first line should have read 01:59:59 EST instead of 02:59:59 EDT.

I'm looking for human readable database of future DST changes: Europe/Roma changes DST 29rd March 2009 Europe/Paris changes DST 29rd March 2009 and more and more...

Do you know a software or/and online website which give me these infos in one page ?

World Time Explorer is a program I made, it has a report for currently 512 distinct timezones with this format: (254) Cuba, Havana (GMT-5) ® - Daylight Saving is active 17.24.00 Sunday 29. March 2009 -0400 EDT DST start : 0.00.00 Sunday 8. March 2009 -0500 EST DST end : 1.00.00 Sunday 25. October 2009 -0400 EDT You can sort output on Country, City, GMT offset, original order (country+city), Daylight saving start date, daylight saving end date, or ISO 3-letter country code. Also it is possible to format the date/time format as you want. You will get one entry for each state above for some countries though, even they are not different this year, in other words has same GMT offset and same start and end date. It is 30-days shareware however, and making this report for other years than 1950 and current year requires a license. But your basic needs should be covered for free. Note that it only runs in Windows. Download from http://www.worldtimeexplorer.com/download.html Regards, Jesper Nørgaard Welen No virus found in this outgoing message. Checked by AVG.

Excellent! How do I get this function to read the file a visitor uploads, instead of just providing the information from php's separate implementation of the zoneinfo data? I didn't think that was possible, so I used the routines I wrote long ago for the same purpose.

Do you realize that PHP has this information already embedded? Since PHP 5.1 we bundle a compressed/archive version of the Olson database and use it internally for all date/timezone operations. It's quite trivial to generate this data: <?php $a = new DateTimeZone( "America/New_York" ); $ts = $a->getTransitions(); var_dump( $ts ); ?> with kind regards, Derick -- http://derickrethans.nl | http://ezcomponents.org | http://xdebug.org twitter: derickrethans
