Is there any way to provide a custom toString pattern? I have

LocalDateTime

which I want to serialize with

yyyy-MM-dd HH:mm:ss

.

Not at the moment, working on it right now. But this format is simple enough, you just can do

localDateTime.toString().replace("T", " ")

.

Is there a YouTrack issue on this, so I can subscribe to progress?

We use Github for the

kotlinx-datetime

issue tracker. There are many issues regarding this, choose whichever you like! https://github.com/Kotlin/kotlinx-datetime/issues?q=is%3Aissue+is%3Aopen+label%3Aformatters

Nice, thanks 🙂
