🌻 Lovelace UI • Minimalist

Hi all - thanks for all of your great work, very happy with how my dashboard has turned out.

Hoping someone can help with the custom card card_input_datetime. Is anyone using this card? I have had a search and spent some time trying to understand it and struggling.

When I use this, the increment and decrement seem to convert my input_datetime to strange numbers. Looking at the template, I can see that the

entity.attributes.timestamp

is converted, and subtracted by different values (e.g. 4500).

I modified this to try to understand how it was all pieces together and changed the first button to - 600 (decrement) and the third to + 600 (increment). This then increased and decreased the time value by 10 minutes, but every second click converted the hour between 24 hours!

Is there something up with my setup, or is there some incompatibility with the card_input_datetime?
