After day light time change, the WDMB (version 2) does not update this change. I changed this using its web interface. However, this change was removed and returned to the original time after reboot. any one have way to change it and keep it after reboot?
Thanks

"Someone oughta put a bomb under daylight savings"
I too suffer from this problem, the most likely fix seemed to be to edit "/etc/TZ" where the default is "EST-10EST,J300,J88" to read "EST-10EST,J280,J95". That's assuming that J*** refers to the number of the day of the year that DST changes. However this change is not persistent, after a reboot it is changed back to the default. Changes to "/etc/ntp.conf" also don't seem to persist although at least the webui allows me to set the one server to "au.pool.ntp.org"

well, my simple solution is to set time using the web interface and disable ntp at /etc/init.d/network_server.sh

It seems working so far

Yeah, this one is a bitch. Presumably we are doing daylight savings differently this year so the time zones in /usr/share/zoneinfo just don't work.

Irritatingly, this screwed with my transmission cron jobs and now I am over quota… grrr.

a quick clarification.
this doesn't owrk. ntp must be running.
I keep the static ntp server by change it at /etc/default-settings to au.pool..ntp.org. But the day light saving does not reflected.

this issue occurs on my MBWE in spring.
I changed the content of /var/etc/TZ (there is a symbolic link in /etc/TZ). I took the new value from http://wiki.openwrt.org/OpenWrtDocs/Configuration#head-a7708420e79025405daa939605108397c2bd7343

on my MBWE the old value was CET-1CEST,J90,J300
and I changed it to CET-1CEST-2,M3.5.0/02:00:00,M10.5.0/03:00:00

Now it seems to work for Germany.

Regards,

Thanks JpgOrganizer, that worked a treat.

For anyone wondering, the string for Sydney, Australia should be: EST-10AEDT-11,M10.1.0/02:00:00,M4.1.0/03:00:00

I set mine to:

CST6CDT,M3.2.0/02:00:00,M11.1.0/02:00:00

To handle today's time zone changes. Done anyone have the template for the positions? All I can think of is that:

CST6CDT - 6 is the UTC offset in CST

Daylight Savings Start
M3 - March
2 - Second Occurance
0 - First Day of change (Sunday)
/02:00:00 - Time when change takes place

Daylight Savings End
M11 - November
1 - First Occurance
0- First Day of change (Sunday)
/02:00:00 - Time when change takes place
