Three Regression Test Problems involving dates

Set forth below are three regression test failures encountered on RedHat
6.0. All involved differences between expected and actual dates. The
actual date is the date the test was run:

If PostgreSQL failed to compile on your computer or you found a bug that
is likely to be specific to one platform then please fill out this form
and e-mail it to pgsql-ports(at)postgresql(dot)org(dot)

To report any other bug, fill out the form below and e-mail it to
pgsql-bugs(at)postgresql(dot)org(dot)

If you not only found the problem but solved it and generated a patch
then e-mail it to pgsql-patches(at)postgresql(dot)org instead. Please use the
command "diff -c" to generate the patch.

You may also enter a bug report at http://www.postgresql.org/ instead of
e-mail-ing this form.
