Summer-/Wintertime autochange

kromonos · 2010-11-01 20:25:49

Where can I find option, that a fluxbb board automaticly changed from Summer- to Wintertime?

There is no automatic function which switches daylight saving time on or off.

There is an option in your profile, which adds an hour, if you check it.

Could we not use the parameter "I" from the date function in PHP (Whether or not the date is in daylight saving time) ? It's quite frustrating to have to ask at every members of our board to check / uncheck this checkbox twice a year

Here a contribution from fluxbb.fr, who must work for French users, and surely could work for different country : http://fluxbb.fr/forums/viewtopic.php?pid=94349#p94349

Hello,

The main problem with date handling and possible automation transition winter time <-> summer time is that we should abandon support for PHP 4 to use only PHP => 5.2.0.
Indeed, the DateTime class and DateTimeZone (and their related functions) are active only since PHP 5.2.0.

Using these classes, it is quite possible to fully automate the scheduling passes Winter <-> Summer whatever was the servers and clients.

Because that reflects the truth with regard to the timezone for the server, not the timezone for the user. Since users are in different timezones and different physical locations, DST kicks in at different times.

Which would be fine for a country specific site such as fluxbb.fr, but not really for a more international site. As Otomatic said, using DateTimeZone would be a good solution if we don't need to support outdated versions of PHP 4, so if would be a good feature to add in FluxBB 2.0, though not the 1.4 branch.

To deal with the least possible error automatic passages from and to DST and standard time, users should define for the database, users table and field timezone not a timezone location (UTC UTC +01:00, UTC-05: 00, etc.). but a true Timezone: Europe/Paris, America/New_York, America/Argentina/Ushuaia, Asia/Tokyo, Asia/Dubai, Africa/Lome, Pacific/Honolulu, etc. corresponding at date.timezone = Europe/Paris from php.ini or date_default_timezone_set() function.

At that time, a code like:

$date_default_save = date_default_timezone_get();
date_default_timezone_set($pun_user['timezone']);
if(date('I')) .... // It is summer time in the user
....
date_default_timezone_set($date_default_save);

would automatically handle DST passages.

But... does not work in PHP 4
