Supporting ZonedDateTime

[sam-mfb]

It seems like adding support for ZonedDateTime is gated by there currently not being a way to map to two database fields in Dapper.

I've made a post on the Dapper repo to see if there is any interest in reviving that question, and so I figured I'd cross post here. If it gets any traction over at Dapper, it feels like it would then be pretty simple to add here. (I'd be willing to take a first crack at it).

Dapper issue

Of course, if anyone has any thoughts on how to do this without a change to Dapper, that would be interesting. Currently, though it seems like the only way is to create an intermediary type that breaks apart the ZonedDateTime type.
