I ended up using 4 maps for now.  If you have a better idea (without
resorting to external utilities) I'd love to hear it:


    ## $time_local is in the format: 28/Oct/2014:11:00:04 -0700
    map $time_local $date_year {
        ~^\d\d/\w\w\w/(?P<substr>\d\d\d\d)     $substr;
    }

    map $time_local $date_month {
        ~^\d\d/(?P<substr>\w\w\w)              $substr;
    }

    map $time_local $date_day {
        ~^(?P<substr>\d\d)                     $substr;
    }

    map $date_month $date_month_numeric {
        Jan          1;
        Feb          2;
        Mar          3;
        Apr          4;
        May          5;
        Jun          6;
        Jul          7;
        Aug          8;
        Sep          9;
        Oct         10;
        Nov         11;
        Dec         12;

        default     $date_month;
    }

    access_log     
logs/$host-access-$date_year$date_month_numeric$date_day.log
standard_log_format;
