Odd error in timestamp processing

Recently we transferred our database from a 7.1 system to a 7.2 using:

 $ pg_dump -h old_host | psql

During this, we saw this message:


ERROR:  copy: line 15926, Bad timestamp external representation
'2002-07-21 06:54:60.00-04'

(It's the '60 seconds' part of the timestamp that is causing the problem,
I'm sure.)  How might this have happened?  Some kind of rounding error?
