in 1887 Voigt set forth an equation, t' = t - vx/c^2, which changed
the value of t at x of a stationary system into t', where v denoted
the velocity of the light- source relative to the given system. In
1904 lorentz called this the 'local time equation"; but to him t'
denoted the time of a system moving at v on X of the stationary
system, and x denoted the position of the clock at the time t. In 1905
Einstein defined a method by which clocks of a given system could be
set in order to measure the speed of light as a constant in any
direction, regardless of the state of motion of the system itself.
In 1907 Minkowski generalized Einstein's method of setting clocks
and then restricted the local time offsets to clocks moving in a non
Y,Z direction. The greatest amount of offset per successive clock
compared to the origin clock of that system was then on X, the
direction of the system's motion relative to the viewing system.
Hence, to know the "time" of a given system one has to know which
clock to look at. That requires one to know the co-ordinates of that
clock in its own system. Therefore, to know the "time" t' of a moving
system you have to know the x', y', z' location of the clock in that
system.
Calling t a "fourth co-ordinate" in a co-ordinate system in which x,
y, and z are spatial co-ordinates, Minkowski invented 4d *spacetime*,
in which 3 dimensions are spatial and the fourth is for time. Its
only value is that it obeys the above explained requirement that the
time of a given system is given by a clock at x,y,z of that system.
All of this is fully explicated in A Flower for Einstein and
elsewhere, by Gerald Lebau, otherwise know as
