[time-nuts] Small time server for mobile use.

Hi sorry for a possibly OT post.   
Has anyone had practical experience with small commercially available time servers / ntp servers suitable for mobile  use in a vehicle.  

 The use case is I am in need of an accurate (ie.  within 100 ms) time source for several pc's in moving vehicle.    Being able to run directly off a 13.8 or 28 VDC  source would be a major plus but AC power is also available.

Hold over if there are gaps in GPS coverage is also a major plus.

We already have a GPS with a 1 pps output, but an integrated box with it's own GPS would be best.

Yes I am aware I could feed a 1 pps signal into a laptop and use that as a time server and I may end up going that route.

There is a small Ethernet LAN in the vehicle.  The pc's currently get their time via a wireless connection to various NTP servers.   I need to be able to ensure accurate time on the PC's if there is no wireless coverage.


This is for a one off project so piecing together various parts is an option but a single box COTS solution would be nice.  I've found a few candidates via web searches but would welcome any feed back.

Thanks in advance
