Poof! You're on Earth
#3
I've often thought that, given modern knowledge of stellar and planetary motions, it'd be "relatively easy" to construct a device which a time traveler could use to observe the night sky and determine the exact time and location anywhere on the Earth's surface so long as they're within a few thousand years of now. Beyond that, errors in our models and chaotic effects in planetary orbits and rotations (like those requiring our current use of leap seconds) would make determining the precise date and time more difficult. Of course, if stars and planets aren't in quite the same locations or orbits, that'd make it quite a bit more difficult, too.
