I'm trying to source an atomic clock/time server that supports both ntp and sntp.

The main difference between SNTP and NTP is that SNTP doesn't provide the error-check and filtering functions that NTP provides. Cisco routers and switches use NTP and allow for all error-checking and filtering functions provided by NTP v3.

Unfortunately not all Cisco IOS versions support NTP v3 eg. (Cisco 1751 Version 12.2(1r)XE1 and Cisco 1721 Version 12.2(7r)XM2). As I don't have a PICA account I'm unable to download the latest IOS versions hence the reason I need to source an atomic clock/time server that supports both NTP and SNTP.
