Is there a way to create a variable in Houdini and have access to it from anywhere?

Sort of like the Houdini Global Variables?

I would like to create and store a datetime object data from a Pre-Render Script, then do a delta for a Post-Render Script (to compute load time).. yet it errors out because I'm unable to access the datetime object that I created in the Pre-Render stage.

I'm hoping to not create external text file logs as this is just a straight forward timestamp check.

Just minutes after posting, I may have found a good lead..
Looking into node UserData now

Hopefully I'm on the right track >_<

EDIT: yup, got it working using this )

For Python Globals…I like to use the Python Source Editor ( under Windows tab ).

I put my globals variables and/or functions there and simply use hou.session to access/set them, e.g.

In Python Source Editor:

Then I can do something like this in a python paramter script:

Thank you for the tip babaj!
That sounds more Global to me, I will use it next time for sure
