> In PostgreSQL, Quantities of days, hours, minutes, and seconds can be specified without explicit unit markings. For example, '1 12:59:10' is read the same as '1 day 12 hours 59 min 10 sec'. For example:
> {code:java}
> maxim=# select interval '1 12:59:10';
> interval
> ----------------
> 1 day 12:59:10
> (1 row)
> {code}
> It should allow to specify the sign:
> {code}
> maxim=# SELECT interval '1 +2:03:04' minute to second;
> interval
> ----------------
> 1 day 02:03:04
> maxim=# SELECT interval '1 -2:03:04' minute to second;
> interval
> -----------------
> 1 day -02:03:04
> {code}
