asterisk users - Aug 2005 - Polycom 1.5.2 firmware NTP problems

I'm running SIP 1.5.2 firmware with a 2.6.2 bootrom on a mix of Polycom
500s and 501s. I'm having a problem with NTP and I'm not sure if
it's a
configuration issue or a bug in the firmware.

I've got the NTP server and GMT offset set in sip.cfg. However, not all
phones are in the same timezone. I was under the impression that I could
override the offset on a per-phone basis (and would expect it to update the
xxxx-phone.cfg file). This doesn't seem to work though.

If you change the GMT offset (with or without specifying an NTP server on
the phone) and reboot, it shows the right time for a while, then after a
few minutes (or an NTP sync maybe?) it reverts back to whatever's specified
in the sip.cfg file.

My experimentation so far has been limited to changing the values from the
phone, not the web interface, but the "problem" IS reproducable. My
next
step thoughts are to add in the OVERRIDES entries manually to
xxxx-phone.cfg and see if it makes any difference but wanted to check if
anyone else has experienced similar issues with this new firmware release?

Thanks in advance

I would suggest just making small .cfg files containing only the 
gmtoffset and load it before the master sip.cfg file, then point the 
phones at the proper gmtoffset file. Much safer than making the change 
on the phone itself.
