hey there Nanog, I am trying to buy a GPS based NTP server like this one
https://timemachinescorp.com/product/gps-time-server-tm1000a/ but I will be placing this inside a data center, do these need an actual view of a sky to be able to get signal or will they work fine inside a data center building? if you have any other hardware requirements to be able to provide stable time service for hundreds of customers, please let me know. mehmet
