Works as expected here; check the headers of this message.
I have postfix 2.6-20080216, but that shouldn't matter for
this test.

Do you have any received_override_options defined in master.cf?

Is the Subject warning logged as you defined?

Are you sure your mail had a Date: header to begin with?

my header_checks contains:
/^Subject: / WARN
/^(Date:.*)$/ REPLACE X-Submission-$1

When I send a mail, postfix logs:
Mar 14 11:00:20 mgate2 postfix/cleanup[98038]: EE83A7978A8:
replace: header Date: Fri, 14 Mar 2008 11:00:17 -0500 from
