Why don't you just declare your timestamp columns as timestamp(0),
so that the extra decimal places are suppressed?

I doubt it. There have been a heck of a lot of bug fixes in the JDBC
driver since 7.1, so even if there aren't any compatibility issues to
worry about (which seems unlikely), it would be much better to use the
up-to-date driver.
