DST Website Timestamps Off One Hour

[Noordfrees]

Since the daylight saving time came active, all timestamps in the website are off by one hour for me: For example, a PM that arrived at 19:58 real time (as listed correctly in my e-mail) is shown in the list of PMs to have arrived at 20:58.

I'm in the German time zone with summertime (CEST, UTC+2). "UTC +02" is also what my profile page shows (I always have the checkbox to use the browser timezone on login active). Maybe the website applies the DST shift on top of a timezone that already accounts for DST?

I'll look into this... Damn time

:( Just noticed there's still (or newly) a similar problem: timestamps are shown correctly while logged in (with the checkbox to save the browser's time as profile time active) but are shown one hour off from the local time while not logged in.
Example: this post was done by me at 8:58 CEST, and when logged in it shows and when logged out it shows as

It is not possible (without much effort) to estimate the time zone of a not logged in user. To accomplish this we have to use IP-address databases to find out which IP-address is in which time zone. Because this is privacy related we shouldn't do that imho. Moreover this is vague anyway, because if the user is behind a proxy the IP-address might looks like the user is sitting in the USA although the real user is sitting japan.

But the login page already determines the user's time zone somehow for the "Looks your time zone is UTC +2.00" checkbox, so why can't we use that?

Yes, probably we can use the same determination of the time zone for all users. For the login page we use javascript, but if a user has disabled javascript it does not work:

AFAIK there is no method to get a users correct time zone under all circumstances.

A solution might be to use the javascript snippet also for not logged in users and for users who disabled javascript we just add UTC to each time display, e.g. for your example it shows then Postet at today 6:58 UTC
