I need to have sub millisecond accuracy, does anybody has any recommendations? Is it possible to switch the oscillator and to what? And what type of oscillator do the boards come with?

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.
