2 questions:

• plans to support an origin option for int -> date32 casting?

• plans to support double -> date32 casting?

  Currently the casting from integer to date works, but assumes epoch (1970-01-01) as the origin. 

  > a <- Array$create(32L)
  > a$cast(date32())
  Array
  <date32[day]>
  [
    1970-02-02
  ]

  Would it make sense to have an origin option that would allow the user to fine tune the casting? For example, in R the base::as.Date() function has such an argument

  > as.Date(32, origin = "1970-01-02")
  [1] "1970-02-03"

  We have a potential workaround in R (once we support date & duration arithmetic), but I was wondering if there might me more general interest for this.

  A secondary aspect (as my R example shows) R support casting to date not only from integers, but also doubles. Would there be interesting in that? Need be I can split this into several tickets.

  Are there any plans in either of these 2 directions?
