If we have a column that's supposed to be a @KomapperUpdatedAt but it's recorded as an Int (unix time stamp), can komapper handle that? Maybe kotlinx.datetime's Instant?

[Toshihiro Nakamura]

Komapper cannot handle an Int as a @KomapperUpdatedAt clumn.
@KomapperUpdatedAt is supported for the following types:
- java.time.Instant
- java.time.LocalDateTime
- java.time.OffsetDateTime
- kotlinx.datetime.Instant
- kotlinx.datetime.LocalDateTime

[dave08]

Any way to get it to work with some kind of adapter?

[Toshihiro Nakamura]

Currently, no.

[dave08]

I would have expected that a

DataTypeConverter<Instant, Int>

would support this... since in the end I'm mapping to an Instant in the data class...?

[Toshihiro Nakamura]

Komapper processes @KomapperUpdatedAt and generates timestamp assignment code at compile-time for efficiency, so Komapper cannot use DataTypeConverter<Instant, Int> which is runtime information.
