Could you expand on this? Do you have the serde feature enabled?

@quodlibetor HI, I do have serde feature enabled I would like to be able to serialize Option<NaiveDateTime>,

but I cannot find equivalent ts_milliseconds_option serializer for NaiveDateTime

[quodlibetor]

Ah, yes I see. I agree that that should exist. I'd be happy to take a PR implementing it, or I will add it eventually, but there are some larger things I'm working on that means I won't be able to do it immediately.

As a workaround you should be able to deserialize to a DateTime<Utc> and just extract to a naive time with exactly the same performance and semantics.

Fixed in #664 (released in 2022 as chrono 0.4.20).
