svn log off by one revision?

Hello,

I am trying to figure out why when I try to specify a date range using
the -r flag to the log command, I apparently get one extra entry
returned. E.g. I am trying to get all commits that occurred between
midnight on 12/15 and midnight on 12/16, but I end up also getting the
last commit from *before* the 15th as well.

In the example below, I would expect the first entry return to be r80,
not r80. Can anyone suggest some way to work around this (besides awk)?

$ svn log -v -r {2003-12-15}:{2003-12-16} http://danello2k2/ec-svn
