Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

Geant4 is the wrong place to look. Look in a good textbook on Special Relativity. This is a physics issue, not a geant4 issue.
You probably want "laboratory time", and that would be G4Track::GetGlobalTime(). But beware of its origin if you want to compare multiple events (you can set it in your G4VUserPrimaryGeneratorAction)....
