there is an option under the Windows based DHCP server that causes a client to time sync with a designated time server... I would love to see this added as the default windows time server (time.windows.com) is garbage LOL

Set Option 43 on your DHCP Server as follows:
BF39:1:BF22:swisstime.ethz.ch:BF21:ntp2.sp.se:BF4:1:BF35:3
Explanation:
BF39 is the reference time source. Setting it at 1 corresponds to NTP4 time server.
BF22 is primary time source. In this case it is set to swisstime.ethz.ch which is an NTP server based in Switzerland.
BF21 is the secondary time source. In this case, it is set to ntp2.sp.se which is an NTP server based in Stockholm, Sweden.
BF4 is to enable logging and is set to 1 which is means logging will be turned on.
BF35 is log level. 1 is Minimal, 2 is Detailed and 3 is Errors Only. In this case it is set as Errors Only.
