Time is off on server

I have a windows 2008 server joined to a domain that had its time off by 5 minutes.  I restarted the server and now appears the time is off by 40 seconds but seems to increase in time difference.

The server is assigned a static IP address; however DHCP on DC1 has 042 NTP Server configured in the server and scope options.  DC2 does not have these DHCP configured.  DC1 NTP Servers in DHCP has 192.168.101.7 and 101.8.   Is it OK for NTP to not be configured in DHCP on DC2 but configured on DC1?

If I execute w32tm /monitor on any domain computer is shows the same settings which are:
C:\Windows\system32>w32tm /monitor
xx-xxxx-DC1.corp.local *** PDC ***[192.168.101.7:123]:
    ICMP: 0ms delay
    NTP: +0.0000000s offset from xx-xxxx-DC1.corp.local
        RefID: clock.team-cymru.org [38.229.71.1]
        Stratum: 3
xx-xxxx-DC2.corp.local[192.168.101.8:123]:
    ICMP: 0ms delay
    NTP: +0.0303650s offset from xx-xxxx-DC1.corp.local
        RefID: grom.polpo.org [65.19.178.219]
        Stratum: 3

How can I verify all computers on the domain are retrieving the same time from the domain controller?
How can I verify the domain controller is retrieving time from a reliable source other than time.windows.com?
On all the computers on the network, time.windows,0x9 is shown for NTPServer in the registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\Parameters.  Shouldn't it rather point to one of the domain controllers?

Thanks for any advice.
