@danielmoncada would you mind checking this out please? :)

Based on the activity in this repository it may seem like the original maintainer moved on from this project.

@NetWin - I see that you're quite active, so perhaps you can consider maintaining your fork, and we move over there. Just a thought.

Yeah i was thinking about this aswell. I even published a version under my npm scope already.

⚠️ But i did not test it yet ⚠️

I saw it and tried it.

I ran into #197 and #194 when using standalone components, particularly because it couldn't inject the DateAdapter.

I was able to work around it by adding OwlNativeDateTimeModule as an import to one of the remaining top level @NgModules in the app. Would be good to make this work with standalone components directly though, I'm not sure what needs to be done.

That's great! Okay i will take a look later and check what needs to be done to convert the library to standalone / make it work in an angular app that uses standalone components. I'll post here when i have an update. 👍

Edit: We now tested it and it works fine in 4 different Angular applications for us at work.

So if anyone needs it, feel free to use: https://www.npmjs.com/package/@netwin/angular-datetime-picker

If you encounter any problems, feel free to create an issue here: https://github.com/NetWin/date-time-picker

Regarding the issues pointed out above. We imported both the OwlDateTimeModule and the OwlNativeDateTimeModule into the standalone component that uses the date picker. And it works flawlessly.

I think the reason for these issues is that the Date picker does not work with JS Dates out of the Box. It's implemented in a generic way where you import the components via the OwlDateTimeModule and the DateTimeAdapter via the OwlNativeDateTimeModule. If the latter is missing, there is no way for the components to parse your provided dates, throwing an error in the process.

I'm currently working on a full upgrade of this library. (Strictmode, standalone, signals, improved documentation etc.) but this will take some time as i have to get familiar with the codebase first.

I'm still here. I will merge this and publish.

I apologize for the absence, been pretty busy at work.

published, thank you @NetWin for the PR
