For time, 00 seems a reasonable default for all values; clearly document the
defaults. Also, having a default makes the code simpler than <level n> plus
<level n-1>. (Not to mention explaining it.) ;-)
SELECT to_timestamp( minutes := 19 ) -- error (year not specified)
SELECT to_timestamp( year := 2000, minutes := 19 ) -- 2000-01-01
00:19:00.0000-07
