Add high-resolution timestamps to log files for debug situations
----------------------------------------------------------------

                 Key: QPID-3236
                 URL: https://issues.apache.org/jira/browse/QPID-3236
             Project: Qpid
          Issue Type: Task
            Reporter: Kim van der Riet
            Assignee: Kim van der Riet


In some performance-related debug situations, it would be useful to see the time between logged
events (in debug or trace mode). However, the standard log timestamp has a 1 second resolution,
and it does not help matters when hundreds of events of interest all occur within the same
second.

I propose to add a #define in qpid/sys/posix/Time.cpp which would change the timestamp printed
by the outputFormattedNow() method to an unformatted second/nanosecond output. This define
would be uncommented and compiled in when needed, but remain commented out for normal use.
A comment would explain its use.

I am sure an equivalent change could also be made to the windows version in qpid/sys/windows/Time.cpp.
