Subject: [PATCH] A possible 'fix' for
 https://github.com/sahlberg/libiscsi/issues/415 This patch adds a timestamp
 before each logged line. That could help correlating a logging to a
 network-trace. Because of offsets in time between the tracer and the test and
 the DUT, this does not always help.
