 perfdhcp expresses the packet sent and received times in an exchange pair,
 ostensibly, as a duration from the epoch. Using
 to_iso_string(time_duration) should result in:

 HHMMSS.ffffff  where it is hours, minutes, seconds. fractional seconds of
 the duration, so we should it expressed since the epoch.  The actual
 values for hours, however is not accurate as can be seen from the
 following stdout excerpt:

 sent / received: 53746523458.837044 / 53746523458.851693

 which is 5374652 hours since the epoch.  This value appears to be wrong as
 it equates roughly 613 years.

 What would be more useful would be expressing the durations as "since
 process start time".  It would also be helpful to display the packet sent
 and/or received as date/time to facilitate correlating these entries to
 server side logs/events.

 Perhaps:

 sent/received  (sent timestamp) / (recvd timestamp) diff: (duration
 between)

 there are any number of alternatives.
