Not really a long time.  Once out of the atmosphere, a 1 gee maneuver
drive with contragrav could get to escape speed from zero in just over
an hour.  That's not much when comparing with the time it takes to get
from and to Jupiter's 100D limit (about 2 days at 1 gee).

A ship leaving the atmosphere at orbital speed without contragrav
would get there at about the same time, if it survived the procedure.
