It looks like DateTime<Tz> impls serde::Serialize, but not DateTime<Local>
the trait `distribution::_IMPL_DESERIALIZE_FOR_Distribution::_serde::Serialize` is not implemented for `chrono::datetime::DateTime<chrono::offset::local::Local>`
Is this an oversight, is there some magic to get it to work, or...?
You can't serialize a DateTime<Local> because there is no timezone information. If you wish to store a raw date without timezone information, use a NaiveDateTime.
