I wrote this simple watermark
IPython magic function to conveniently add date- and time-stamps to my IPython notebooks. Also, I often want to document various system information, e.g., for my Python benchmarks series.
The watermark
line magic can be directly installed from my GitHub repository via
In [2]:
%install_ext https://raw.githubusercontent.com/rasbt/watermark/master/watermark.py
To load the date
magic, execute the following line in your IPython notebook or current IPython shell
In [2]:
%load_ext watermark

arguments, type
