| * and returns the apr_time_t number of microseconds since 1 Jan 1970 GMT, |

| * |
| * The restricted HTTP syntax is |
| * |
| * HTTP-date = rfc1123-date | rfc850-date | asctime-date |
| * |
| * rfc1123-date = wkday "," SP date1 SP time SP "GMT" |

| * | "May" | "Jun" | "Jul" | "Aug" |
| * | "Sep" | "Oct" | "Nov" | "Dec" |
| * |
| * However, for the sake of robustness (and Netscapeness), we ignore the |
| * weekday and anything after the time field (including the timezone). |
