1) Can you provide an example?
2) I don't know how to reverse an output interval to it's input value.
That wasn't the ask though:
select interval '2 year 36 hours 15.123456789 seconds';
yields:
2 years 36:00:15.123457
But if what is stored is only months, days, and microseconds what is being requested is to produce:
24 months 1.5 days 15123457 microseconds (or whatever the values stored in those three positions is...)
