[O] Set or update timestamp after evaluation of code block?

[Rainer M Krug]

Hi

I have some code blocks which represent an sequence of
fitting-analysis-plotting. But Sometimes I am loosing track which code
blocks I have evaluated.

Is it possible to set a timestamp (ur update it when it exists already)
when a code block has been evaluated, so that I have e record when it
was updated?

Thanks,

Rainer
