I believe chrony not only checks the time with time servers, it also
compensates in some way for hardware clock drift.
I use it on my boxes. It doesn't seem to talk through IP-masquerading.
So I have chrony running on my IP-masquerading box and have the others
talk to that one.
I no longer have any problems with clock drift.
