NTP sync

My time is supposed to go back by one hour but it didn't and I didn't apply the patch for this on a Solaris box which gets time via NTPD from outside. I logged on to the box and see time off by one hour - is it because I didn't apply the patch or is it the NTP server one hour off (an error in NTP server)?

Now I can set my local time one hour forward just fine but as soon as I start NTPD, it goes off by one hour again! And if the time difference between the local time and NTPD is high (1 hour), the NTP daemon dies.

Does anyone know how to fix this issue? Is there something wrong with the NTP servers I am trying? Is there any way to get around this without applying any patch? I never thought I needed to since I use NTPD.

It isn't ntp's fault and yes it is due to not updating tzdata. In a nutshell your clock will be synced using your local timezone offset unless you use UTC. If you do not want to update tzdata then you could manually change your time zone for the couple of weeks in the fall and spring as required or just use UTC.

BTW I assume your somewhere in the US and your clock is slow by an hour.
