I'm in the time zone of Amsterdam. KDE misreports the time by one hour (behind). I have additional time zones set up in the (digital) clock widget which are correctly reported over mouse hover (e.g. for Tokyo and Toronto). Daylight savings won't take effect until 31 March. If I set the time zone to Berlin (same as Amsterdam), the time for Amsterdam is correctly reported while the time for Berlin is incorrectly reported by one hour (behind). What's going on here?!

As a workaround, I've set the time zone to Berlin, but I've set the clock widget to show the time zone for Amsterdam. As soon as I put the time zone back to Amsterdam, it's incorrectly reported by an hour.

I'm running Kubuntu 13.04 beta, KDE 4.10.1.

is this a KDE thing? doesn't the timezone info just get read from the timezone package?

if log into a diff desktop environment is it's clock correct?

if you use within KDE a non-KDE app to show time (gKrellm, a FF (or other browser) clock add-on)?

Can you please check the contents of ktimezonedrc?
If a file is mentioned for ZonetabCache, and it is under $HOME, /var/tmp/ or /tmp then I suggest logging out and removing this file.
