Date representation

Hi,

I having some problem with the date fields migration from 7.1.3 version to 7.2
version...

In my current version PostgreSQL 7.1.3 on i686-pc-linux-gnu, compiled by GCC
2.96 I get this result

select now();
          now
------------------------
 2002-04-11 12:58:33+02
(1 row)


In the new version  PostgreSQL 7.2 on i686-pc-linux-gnu, compiled by GCC 2.96

SELECT NOW();
              now
-------------------------------
 2002-04-11 13:02:27.943119+02
(1 row)


The date is different in the last part:

2002-04-11 13:02:27.943119+02
         ^^^^^^^^^
Then when I am trying to update this field from ACCESS I have an error and the
entry can't be updated because the dates are not equals.

Someone can help me?

Thanks.
