It happens after about 6-7 hours.  The problem is very consistent.
I am also running 1.0.3.81 firmware on the phones.

Perhaps this is a config problem with ntpd?
here is my ntp.conf:

server clock.isc.org
server time.nist.gov
restrict clock.isc.org          mask 255.255.255.255 nomodify norap noquery
restrict time.nist.gov          mask 255.255.255.255 nomodify norap noquery
restrict 192.168.2.0            mask 255.255.255.0 notrust nomodify notrap
restrict 127.0.0.1

my GS phones are on the 192.168.2.0/24 network.
