where:

127.0.0.1 is the IP address (or host name, if available) of the client (remote host) which made the request to the server.
- The “hyphen” in the output indicates that the requested piece of information (user identity from remote machine) is not available.
- The “hyphen” in the output indicates that the requested piece of information (user identity from local logon) is not available.
[24/Jul/1973:08:32:01 -0400] The server “end time” to process the request. The format is: [day/month/year:hour:minute:second timezone]
- day = 2 digits
