> 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.
