This is a python-based plugin for inserting custom time/date on Notepad++ documents.
- Install the "Python Script" plugin. If you use the Notepad++ Plugin Manager, check where the PythonScript folder has been created (e.g., under %AppData% or %ProgramFiles%) If you prefer, install the PythonScript plugin manually. To do so, you can download the PythonScript plugin from http://npppythonscript.sourceforge.net/download.shtml.
- Save the script to the PythonScript\Scripts folder. In my case it was:
"%ProgramFiles%\Notepad++\plugins\PythonScript\scripts\timestamp.py"
