Thx Joffrey,
it is a matter of DST "day light saving time". So I found a nice function to
get if we are in sommer (true) or
winter (false) time. I want to share it with the list:
Date.prototype.getDST = function() {
var now_local = this;
var jan_local = new Date(now_local.getFullYear(), 0,
1, 0, 0, 0, 0, 0);
var jun_local = new Date(now_local.getFullYear(), 5,
1, 0, 0, 0, 0, 0);
var now_utc = new Date.UTC(now_local.getFullYear(),
now_local.getMonth(), now_local.getDate(), now_local.getHours(),
now_local.getMinutes(), now_local.getSeconds(),
now_local.getMilliseconds());
var jan_utc = new Date.UTC(jan_local.getFullYear(),
jan_local.getMonth(), jan_local.getDate(), jan_local.getHours(),
jan_local.getMinutes(), jan_local.getSeconds(),
jun_local.getMilliseconds());
var jun_utc = new Date.UTC(jun_local.getFullYear(),
jun_local.getMonth(), jun_local.getDate(), jun_local.getHours(),
jun_local.getMinutes(), jun_local.getSeconds(),
jan_local.getMilliseconds());
var now_diff = Math.round((now_utc -
now_local.getTime()) / (1000 * 3600));
var jan_diff = Math.round((jan_utc -
jan_local.getTime()) / (1000 * 3600));
var jun_diff = Math.round((jun_utc -
jun_local.getTime()) / (1000 * 3600));
return jan_diff != jun_diff && now_diff ==
Math.max(jan_diff, jun_diff);
};

Hi Mustafa,
It sure looks like a DST issue. Switching back to winter time happens on
the last Sunday of October!
