That page shows a definition of the term "seconds since the Epoch", viz.
"[a] value to be interpreted as the number of seconds between a specified
time and the Epoch."

Well, it may be "to be interpreted" as such a value, but it is *not* such
a value. As of this writing, its value on my machine is 1043944376, but
that does not mean, or so it seems, that 1043944376 s have elapsed since
the Epoch.
