I don't have a polycomm manual handy, but I think I'd change the
overrideDHCP parameter to "1" and test. You are apparently in the PST timezone?

If that doesn't do it, my next step would be to use ethereal to capture one of the ntp request/response pkts and analyze the content. If that looks okay, then something in the phone isn't right.

Using the same IP for the server on a Linksys SPA-941 everything is correct,
using this configuration on the 501 shows 24 hours ahead.

This is a copy/paste of the exact statements used on a IP600 phone:

<SNTP tcpIpApp.sntp.resyncPeriod="86400" tcpIpApp.sntp.address="134.84.84.84" tcpIpApp.sntp.gmtOffset="-21600" tcpIpApp.sntp.daylightSavings.enable="1" tcpIpApp.sntp.daylightSavings.fixedDayEnable="0" tcpIpApp.sntp.daylightSavings.start.month="4" tcpIpApp.sntp.daylightSavings.start.date="1" tcpIpApp.sntp.daylightSavings.start.time="2" tcpIpApp.sntp.daylightSavings.start.dayOfWeek="1" tcpIpApp.sntp.daylightSavings.start.dayOfWeek.lastInMonth="0" tcpIpApp.sntp.daylightSavings.stop.month="10" tcpIpApp.sntp.daylightSavings.stop.date="1" tcpIpApp.sntp.daylightSavings.stop.time="2" tcpIpApp.sntp.daylightSavings.stop.dayOfWeek="1" tcpIpApp.sntp.daylightSavings.stop.dayOfWeek.lastInMonth="1"

Are you sure you are setting the gmtOffset to the proper number? The above example is for CST, which is -6 hours (or -21600 seconds) from GMT. It is also config'ed with resyncPeriod = 24 hours, meaning the clock is only sync'ed once per day.

What are you using for the above?
