Timestamp in C and Python
A fast one for all of you who don’t want to reinvent the wheel all the time, licensed under the [no-problem-bugger-off-license]. Print timestamps in C or Python, for debugging by print statements, and for when a logging library is just too much.
In C:

There you go.
Btw. if you use my email address from 2000 I’m genuinely impressed. It will not work though.
The Python code was written for Python 1.x since 2.0 came out in october 2000 and this code was written before that. The date is not a joke. And all I had to fix at the last revision (july 2022) was to add parentheses to the print statement, since Python 3.x requires that now.
The boilerplate code can be found on my github, in case you are interested… and still use Emacs.
