Description

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.
