This will avoid some differences when checking in different time zones.
We now run the tests without the '-t' option. This will allow to get
problems/changes in time printing functions.
Update the output of the tests accordingly.
Moreover:
Add the '-#' option to better identify a packet when there is a difference
in output.
The test cases included the timestamp (due to missing -t) and failed
unless run in the same timezone as produced. The failures printed by
print-flags.sh did not make it into the final report because the script
always returned 0.
Strip the timestamps and replace print-flags.sh with some contents in
TESTLIST.
