TIMESTAMP is a PYTHON script 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 simply gives the current time. If you are trying to do careful timings of the speed of execution of a computer code, this may not be very accurate, especially on a computer that uses timesharing.

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.
