It depends on traffic. At about 6:00-8:00am, it would take maybe 1-2 hours. At 5:30-8:00pm, it would be slammed and take 1.5 to 2.5 hours. Any time in between that would take about 30 min. to an hour.
time travel as in which zapping yourself to another time and space?? if so you take as fast as a sec. and as long as FOREVER depending on how fast u could zap yourself. well, good luck and if you get lost just go back where u came from.
