I'm having the same problem with -CURRENT.  I have updated the
zoneinfo files (using misc/zoneinfo) and (re-)run tzsetup, but am
still a hour behind.

  Are you running ntpd?

I am.
(If it matters, I have rebooted the system since updating the
tz files/settings.)


Robert Huff


Have you checked the ntpd log file for errors, and verified it is 
running.  Often ntpd won't reset the time if the delta is too large, and 
you have to stop nrpd and run ntpdate instead, then start ntpd.

I genuflect in your direction, sir.  That did it.

If you have securelevel greater than 1 the kernel prevent large time
changes.  See man init(8).

However, now I'm curious - isn't this going to be a recurring
problem (admittedly only twice a year) for the non-trivial number of
machines that do run ntpd for various reasons?

Shouldn't be a recurring problem but it can depend on what version of 
FreeBSD you are running.  I've had no problem with 6.X and 7.X updating 
automatically this weekend.

I suspect that it is only a problem for those whose machines are
a) Having the CMOS clock set to local time (instead of UTC)
and
b) Having their computers turned off when the switch to/from DST
   is being made - thus preventing adjkerntz(8) from adjusting
   the CMOS clock appropriately.


Running ntpd(8) will by itself not cause any problems - but in the
above scenario it will not adjust the time to be correct either - 
the jump will be too large.

Hi,

My FreeBSD 6.2 doesn't change to Daylight Saving Time. How should I fix
it?

'zdump -v /etc/localtime | grep 2008' output:
