Neal Richardson updated ARROW-17043:
------------------------------------
Description:
{{date64 + intX}} would be equivalent to {{date64 + intX->cast(duration(unit =
"d"))}} (I guess this is tricky since "s" is the largest duration unit? but
date64 is an integer underneath, we should be able to add another integer to it)
{{timestamp[ms] + intX}} would be equivalent to {{timestamp[ms] +
intX->cast(timestamp(unit = "ms"))}}
etc.
Multiplication and division probably don't make sense, but addition and
subtraction do, at least saves you the trouble of having to convert to a
Duration first.
