This change adds:
year-month-day to the hours:minutes:secondes.{microseconds|nanoseconds}.
It allows to catch more issues with timestamps processing.
For some test using their own display time options, use 'SPECIAL_t' in
options.
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.
