On a side note, I was doing a grep through the server for
apr_explode_localtime() to see where all it was used and came across this
hideously expensive-looking if/elseif/elseif/.../elseif/else block in
mod_rewrite for variable substitution.  Surely there's a faster way to
accomplish that little bit of logic than forty or so strcasecmp's for each
variable (in the worst case)...
