My FRITZ!Box 7390 synchronises properly with the NTP servers, but it does not take the DST ("daylight saving time", in German: "Sommerzeit") into account, that started last night over here in Germany (e.g.).
When I log in to my box, it shows the date (day and time) like this:
$ telnet fritz.box
# date
Sun Mar 25 10:05:09 CET 2012
It should show this instead:
Sun Mar 25 11:05:09 CEST 2012
The time itself is alright, just the DST is not.
- one on its "FRITZ!Box Fon: Internet" subforum: "[Fritz!Box 7390] Umstellung auf Sommerzeit erfolgte nicht",
- one on its "Fritz!Mini, M2, MT-C, MT-D, MT-F, C3" subforum: "Keine autom. Aktualisierung auf Sommerzeit?"; here I found the most thorough description of the situation: "Es ist ein Problem mit der Zeitzone".
Another look inside the box:
The constituents of "M3.5.0" mean this:
# ls -l /etc/TZThe TZ file looks like it's writable, but it's on a read-only filesystem.
lrwxrwxrwx 1 root root 7 Mar 2 16:01 /etc/TZ -> /var/TZ
# ls -l /var/TZ
lrwxrwxrwx 1 root root 19 Mar 25 11:01 /var/TZ -> /etc/default.049/TZ
# ls -l /etc/default.049/TZ
-rwxrwxrwx 1 root root 45 Mar 2 16:01 /etc/default.049/TZ
# cat /etc/default.049/TZ
CET-1CEST-2,M3.5.0/02:00:00,M10.5.0/03:00:00
The constituents of "M3.5.0" mean this:
- The "3" means the 3rd month of the year.
- The "0" means the 0th day of the week, i.e. the Sunday.
- The "5" means neither the 1st through 4th, but the last Sunday.
Looks like AVM's software has a problem with determining the right date for the last Sunday of March in 2012.
On my blog in German I am referring to an article in a German magazine, that shows how and where to change the timezone "manually". (Somebody on the IP-Phone-Forum quoted that article, and that's how I found it.) My fix for 2012: replace that "5" by "4"!
Update 2012-03-26: AVM look like they don't want to announce a fix for this problem within the next couple of days [Link].
Update 2012-03-28: AVM provide a "Labor" firmware update.
