Rails - Dec 2005 - PostgreSQL unit test failure

PostgreSQL 8.1, Win32, Ruby 1.8.2 for Win32 native.
Rails 1.0 gems.
Starting on line 784 of the ''base_test.rb'' file for
ActiveRecord
1.13.2 is "test_default"
When I run the unit tests for ActiveRecord against Postgres,
everything passes except for this test.  It looks like modified_time
returns a default of ''nil'', rather than Time.now, as it
should.
Is this a known issue? I tried searching the fault tracker, but didn''t
find anything.

Using native PostgreSQL
Loaded suite base_test
Started
...........................E....................................................

Finished in 1.875 seconds.

  1) Error:
test_default(BasicsTest):
NoMethodError: undefined method `strftime'' for nil:NilClass
    base_test.rb:790:in `test_default''

103 tests, 256 assertions, 0 failures, 1 errors

Thanks,
