Turns a timestamp as it stored in the paradox file into human readable
format. Paradox timestamps are the number of miliseconds since 0001-01-02.
This function is just for convenience. It can be easily replaced by some
math and the calendar functions as demonstrated in the following example.

The Julian day count as passed to <span class="function"><a href="function.jdtogregorian.html" class="function">jdtogregorian()</a></span>
has a different base of 1.1.4714 b.c. and must therefore be calculated
by adding 1721425 to the day count used in the paradox file. Turning the
day count into a timestamp is easily done by multiplying with 86400000.0
to obtain miliseconds.
