Hello, is it recommended to use GMTDate in multiplatform projects?? Since kotlinx-datetime still did not implement formatting features!

[Gijs van Veen]

If you only need support for Datetime in mobile, you could use our library Kaluga: https://github.com/splendo/kaluga/tree/develop/base

[Gijs van Veen]

It supports formatting/parsing and localization

Just use the platform specific formatters

[Elio Maroun]

So I give my presentation model date as string and in every platform I do formatting

[hfhbd]

No, use Instant from kotlinx-datetime. You only need the formatter/formatting for interacting with the users, eg in Swift, so use the platform native formatters for displaying/input but Instant in your Kotlin business logic code

[Elio Maroun]

cause in my app I am building a calendar using java.time library using localdate and localdatetime

[Elio Maroun]

So I will transform Instant to LocalDateTime?

[hfhbd]

Yeah, for example

[Elio Maroun]

So my presenter model will be Instant and formatting it inside the UI

[Elio Maroun]

data model is string

[hfhbd]

Yeah, but I still don't get it why you want to use a string in your data model

[Elio Maroun]

domain model should be date instant also

[Elio Maroun]

data model is the response from the server

[hfhbd]

Ah okay. If the response uses ISO 8601 you can use kotlinx serialization and Instant too

[hfhbd]

Or write your own serializer, if you want

[Elio Maroun]

"2022-10-18 08:30:00" server response

[hfhbd]

That's not iso 8601 but you simple could use replace(" ", "T")

[hfhbd]

or change the response if you control the server

[Elio Maroun]

okay thank you!!
