TIMESTAMP is a Mathematica routine 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.
In order for the package to be accessible, the package file must be placed in the appropriate place. A typical place is the "Applications" subdirectory of the "User Base Directory". These are directories set up by Mathematica. You can find out where the User Base Directory is by the Mathematica command:
$UserBaseDirectory
Then you need to copy the package file to the "Applications"
subdirectory of that directory.
Once the new package has been placed, you should probably run Mathematica and direct it to rebuild the Help database. This will serve to update Mathematica's internal information so that it can explain how the functions in the package are called.

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 Julia version and a Mathematica version and a MATLAB version and a Python version.
