## Which issue does this PR close? - Closes #16285. ## Rationale for this change This commit adds support for Arrow Duration types in Substrait plans. Substrait has no equivalent to the Duration type, which only includes time-based information (i.e. some multiple of nanoseconds). However, the Substrait Interval Day type is very similar, it stores day and time-based information. This commit converts Arrow Duration types into Substrait Interval Day types, with a Duration specific type variation reference, so that it can round trip back to a Duration. An alternative approach would be to use a new Substrait user defined type. ## What changes are included in this PR? <!-- There is no need to duplicate the description in the issue here but it is sometimes worth providing a summary of the individual changes in this PR. --> ## Are these changes tested?
