[northwestwitch]

Oh no. I'll start working on a fix now!

[northwestwitch]

I don't get why why this wasn't an issue until now though. Perhaps the connected node stores the date with another format?

[dnil]

Yes, the timing is odd. I would have been unsurprised if it was after like the python version update or a date time library change.

[northwestwitch]

The page now wprks after the the patch release. Closing the issue!
