Bug description:Europe/London is in two timezones
Description:
------------
I was about to create a timezone selector widget with map and select box
with the timezone IDs, but when I asked for the full timezone list with
DateTimeZone::listAbbreviations() I saw that Europe/London is in two
different timezones according to the Greenwich Mean Time:
- "bdst": DST is TRUE, offset is GMT+2 hours (== DST:false and GMT+1)
- "bst": offset is GMT+1 hour and DST doesn't matter, both TRUE (== GMT+0)
and FALSE (== GMT+1) can be found
- "gmt": DST is FALSE, offset is GMT+0. It is GMT of course :)
How can this be possible?
Test script:
---------------
<?php
$dtz = DateTimeZone::listAbbreviations();
die('<pre>'.print_r($dtz, true).'</pre>');
// and search for 'Europe/London' or see description below
Expected result:
----------------
GMT+1 in Summer and GMT+0 otherwise. Something like:
["bst"] => array(25) {
[0] => array(3) {
["dst"] => bool(true)
["offset"] => int(3600)
["timezone_id"] => string(13) "Europe/London"
}
...
}
...
["gmt"] => array(30) {
...
[26] => array(3) {
["dst"] => bool(false)
["offset"] => int(0)
["timezone_id"] => string(13) "Europe/London"
}
...
}
Actual result:
--------------
...
["bdst"] => array(8) {
[0] => array(3) {
["dst"] => bool(true)
["offset"] => int(7200)
["timezone_id"] => string(13) "Europe/London"
}
...
}
...
["bst"] => array(25) {
[0] => array(3) {
["dst"] => bool(false)
["offset"] => int(3600)
["timezone_id"] => string(13) "Europe/London"
}
[1] => array(3) {
["dst"] => bool(true)
["offset"] => int(3600)
["timezone_id"] => string(13) "Europe/London"
}
...
}
...
["gmt"] => array(30) {
...
[26] => array(3) {
["dst"] => bool(false)
["offset"] => int(0)
["timezone_id"] => string(13) "Europe/London"
}
...
}
...
