I'm not sure if I have a common time, but it can take minutes. I'm
not entirely sure how it works in the guts of the GPS, but I think
it remembers which satellites it had sync with before and tries
to go from there. If it's thoroughly confused (eg, the GPS has been
off for a long time, and transported somewhere else), it can take
quite a while. AGPS helps all of this out because it very quickly
talks to the cell towers to get a rough idea where it is so that
the GPS software can have a better idea of where the satellites
for that area ought to be.
At least that's my high level understanding, which isn't anything
approaching expert :)
