Integrating js-joda LocalDate with effect/schema

apologies for a total newbie question -- I just started playing with effect/schema today. I have an existing project that uses js-joda to deal with dates; so for example LocalDate represents a calendar date with no time or timezone information.

LocalDate

LocalDate

does its own serialization/deserialization (

d = LocalDate.parse("2024-06-10")

d = LocalDate.parse("2024-06-10")

and

s = d.toString()

s = d.toString()

). What's the effect/schema way to work with these values? Clearly it's not this

export const TimeEntry = S.Struct({
  id: TimeEntryId,
  userId: UserId,
  date: LocalDate, // nope that's a type...
})

export const TimeEntry = S.Struct({
  id: TimeEntryId,
  userId: UserId,
  date: LocalDate, // nope that's a type...
})

but it's not really clear how I should be thinking about this. Do I need to define a schema for these external objects, kind of how I might create my own TS types to work with a JS library?
