TIMESTAMP is a FORTRAN77 library which prints the current YMDHMS date (year-month-day-hours-minutes-seconds) as a timestamp.
This is useful when documenting the run of a program. By including a timestamp, the output of the program will always contain a clear indication of when it was created. Other indicators, such as the file modification timestamp, may be misleading or subject to unintentional modification.

TIMESTAMP is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a JAVA version and a Mathematica version and a MATLAB version and a PYTHON version.
