svn log output doesn't seem to obey -r arguments

If I run this command:

svn log -v URL -r {2007-05-01T02:00:01}:{2007-04-30T02:00:01}

I get this output:

------------------------------------------------------------------------
r4019 | user@HERE.LOCAL | 2007-04-27 10:34:12 -0600 (Fri, 27 Apr 2007) | 2 lines
Changed paths:
   M /Display.xml

Why do I get that when it is outside of the date/time range specified?

TIA!
