My docs say that it is "the difference, measured in milliseconds, 
between the current time and midnight, January 1, 1970 UTC".

Further, it says to review the Date class doc for more info. That doc 
also implies it is UTC, but in a "modified" way.

I must disagree, the docs are not precise!

A difference is between two points, here in the continuum of time. :)
"midnight, January 1, 1970 UTC" is one of these points, where is the other?

All that is said is "current time". But what is current time? It could 
be UTC again or some local time, adding an offset to the UTC value. The 
Date class doesn't bring more light on that topic either.

It's the number of seconds from midnight, January 1, 1970 UTC, full stop.
Regardless of your time zone, if you adjust that time to your local time
(e.g. for Eastern Standard Time, 7:00pm, December 31, 1969 EST) and then
adjust the time returned by System.currentTimeMillis(), the difference is
still the same number of milliseconds.  The value returned by this function
does not change based on your time zone.
