I wasn't referring to dt/d(tau).  What I meant was this:  people
keep talking about "moving" through time, as though they were going
some "place" (in space-time, I presume).  Does this make sense?
Are we, in fact, moving through space-time?  If we ARE moving
through space-time, with reference to WHAT are we moving?  Doesn't
special relativity actually say that we are NOT moving at all and that
any point in space-time is not especially unique?  Doesn't five
minutes ago at this terminal exist at five minutes ago at this terminal?
Isn't the structure of space-time static and just there?
