Time zones

[Botffy]

The extension currently assumes all times on the Timeline page are in the same time zone as the computer running the browser. If you've ever traveled outside your current time zone, that's not the case.

This is tricky, since there's no time zone or geo information in the DOM, so we can't actually determine the time zone of an activity.

A possible solution might be to fetch the original JSON about the location information, and consult that while parsing the DOM.
