dateTime 
Transforms ISO date and time string to Date and serializes back to ISO string.
ts
import { Model, column } from '@outloud/model'
class User extends Model {
  @column.dateTime()
  declare createdAt: Date
}
const user = User.create({
  createdAt: '2023-11-17T15:24:06.764Z'
})
user.createdAt // Date
user.toJSON().createdAt // '2023-11-17T15:24:06.764Z'Custom serialization 
It's possible to define custom serialization logic for dates.
Configure serializer 
Globally configure serializer once in the app.
ts
import dayjs, { type Dayjs } from 'dayjs'
import { configure } from '@outloud/model'
configure({
  date: {
    deserialize: (value: Date) => dayjs(value),
    serialize: (value: Dayjs) => value.toDate()
  }
})Use new type 
ts
import type { Dayjs } from 'dayjs'
import { Model, column } from '@outloud/model'
class User extends Model {
  @column.dateTime()
  declare createdAt: Dayjs
}
const user = User.create({
  createdAt: '2023-11-17T15:24:06.764Z'
})
user.createdAt // Dayjs
user.toJSON().createdAt // '2023-11-17T15:24:06.764Z'
