The js file is created in “Assets”. I assume those are theme assets?
I loaded it in the “standard-page.html” file using a script tag. I just tried adding it to the Native libraries but that didn’t work either.
@jeremy.deceuster if you’re still having issues, creating a minimal clone link that shows your app structure will be helpful when providing specific advice.
you might also want to share the javascript helper function.
The Python datetime module might already have what you need.
