I see, thanks for these infos.
The timestamp is recorded here in "/var/lib/sudo/thierry/3" which would
correspond with /dev/pts/3.
I am already using an alias for sudo:
alias sudo *sudo -p Password: $*
and with it, "sudo tty" always return "/dev/pts/3", but I have anyway to
reenter password at each time.

I think this is same as using "*sudo" which work badly too.
