Refresh now() templates on second=0

[amelchio]

Breaking change

Proposed change

Beta feedback on #41147 is that it would be better if now() causes templates to refresh when the minute changes. This will be more useful for example for comparisons with input_datetime and it is also easier to debug things when you know when to expect the change.

Tested and working as expected. Thanks 👍

I'll get a frontend PR going since the phrasing will need to be updated.

Great, thanks. We should probably also update the Breaking Change in #41147.

I will look at updating the documentation, I think we missed that with #41147. I plan to mostly remove the text about working without entities and just add a note that now() updates each minute.

Updated documentation: home-assistant/home-assistant.io#15360

Nice. I forgot to actually put in the PR 🤦 when updating #41147. I'll check my local branch that is still useful and see if there is anything as soon as I have a free moment.

I updated the breaking change section in #41147

The 0.117 release blogpost claims,

Please note, if you have a time-based template where you do not want it to update periodically it will now have to be reworked to not use now().

But there are no recommendations or links on how to do that. ☹

[amelchio]

@acshef We don't know what to recommend because we have no examples where this would be needed. It will in any case depend on the template, there is no recipe.

As it is really a support question please ask in the forum – but feel free to tag me and I will have a look.
