Yes, but the applications running on a standalone machine
will use the same API's as any other POSIX machine.
Therefore, unless you want two seperate API's, one
for standalone machines and one for network-connected
machines, and then also require that applications written for
one are incompatible with applications written for the other,
then it is best to meet both requirements.
So I don't believe this has anything to do with whether
or not a standalone machine drifts due to not having a
caesium clock on board.
