Giant lines deleted. OK, it looks like the 1332471600 is a unix
timestamp, not a SQL timestamp.
First thing I'd do is make a staging table to hold all these rows.
Declare that second field as bigint and so on, so you can load all
your rows at once.
After all the rows are loaded into a staging table, then you can start
using various pg functions to convert from unix timestamp to sql
timestamp etc.
http://www.postgresql.org/docs/8.4/static/functions-datetime.html
Search for the keyword "epoch" on that page for how to convert back
and forth from unix timestamps.
