Bob's lastmodified plugin for Blosxom has a subtle bug.
Last-Modified: Sat, 1 Nov 2003 20:45:57 GMTSee the difference? Helps to have it lined up; there's a space missing in the Last-Modified header.

Shouldn't much matter, right? Wrong. Apache parses these headers from CGI scripts and tries to fix them up. It can't parse the one without the space, so it silently replaces it with zero and all my pages look like they were last modified 1 Jan 1970. Argh!
