If the drift is constant, then yes. If the oscillator is wandering, then no.
OP could use a PPS signal, and / or stabilize the oscillator (if that turns out
to be the problem). This post (and it's parent thread) has links to info on
both:

I guess the OP needs sub-mS accuracy while disconnected from the net, otherwise
he could just use his stratum 1 server. How long, and under what temperature
conditions, do you expect sub-mS accuracy? Using a PPS from a GPS sounds like
the only option to me to keep sub-mS time while off the grid.
