Hey! anyone know if Exposed supports OffsetDateTime as a column type? or any suggestions how to work around not being able to save a timezone would be really appreciated 🙂

You could make your own type based on an existing one

sample for postgres and kotlin-datetime Instant:

// Custom implementation since Exposed kotlin-datetime timestamp does not use UTC...
public fun Table.instant(name: String): Column<Instant> =
    registerColumn(name = name, type = PostgresInstantColumn())

private class PostgresInstantColumn : ColumnType(), IDateColumnType {
    override val hasTimePart = true

    override fun sqlType(): String = "TIMESTAMPTZ"
    override fun valueFromDB(value: Any): Instant = when (value) {
        is Instant -> value
        is java.time.Instant -> value.toKotlinInstant()
        is java.sql.Timestamp -> value.toInstant().toKotlinInstant()
        is String -> value.toInstant()
        else -> error("Unexpected value of type Instant: $value of ${value::class.qualifiedName}")
    }

    override fun notNullValueToDB(value: Any): java.sql.Timestamp = when (value) {
        is Instant -> java.sql.Timestamp.from(value.toJavaInstant())
        is java.time.Instant -> java.sql.Timestamp.from(value)
        is String -> java.sql.Timestamp.from(value.toInstant().toJavaInstant())
        else -> error("Unexpected value of type Instant: $value of ${value::class.qualifiedName}")
    }
}

thank you!
