The PostgreSQL documentation claims that the range of an 'interval' type is +/- 178000000 years. So why do I get this?

stargreen=> select interval '3280756607 second' ;
      interval       
---------------------
 24855 days 03:14:07
(1 row)

Does that answer look familiar? It should

CL-USER> (+ (* 3 3600) (* 14 60) 7 (* 86400 24855))
2147483647

So, there must be some other way to make Postgres convert from CL universal time to its own time format

stargreen=> select timestamp with time zone '1901-01-01 0:0:0' + interval '3280756607 second' ;
        ?column?        
------------------------
 1969-01-19 04:14:07+01
(1 row)

because the obvious solution isn't one.
