            Bug ID: 255704
           Summary: Feature Request: ipfw: print time in ISO8601 or allow
                    to pass time format string
           Product: Base System
           Version: 13.0-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: misc
          Assignee: bugs at FreeBSD.org
          Reporter: parv.0zero9+freebsd at gmail.com

ipfw with "-t" option currently prints the via ctime, supposedly for human
consumption. That output of time stamp value is far too fractured for me to
easily read and make sense of.

Parsing ipfw output to convert seconds since Unix epoch in desired time format
is too brittle, as output could change depending on the options passed to ipfw.

There should be an option to print the date-time value in ISO8601 format for
easier reading & understanding.

Another method could be to allow user to pass in a custom date-time format
string -- via an option, environment variable, some tunable, etc. -- for ipfw
to print time stamp in that format.
