Poof! You're on Earth

The error bars would get larger the further away from the present day these people are located. Each 'leap second' would represent a distance of 30 metres at the equator, so the uncertainty in longitude would increase by a few tens of metres every time a leap second needed to be added. This would mean an uncertainty of around ten nautical miles every thousand years- not too bad, assuming the rate of change remains roughly constant.
