Here's the two relevant excerpts from the manpage:
-t YYYYMMDDHHMMSS
Display the state of logins as of the specified time.
This is useful, e.g., to determine easily who was logged
in at a particular time -- specify that time with -t and
look for "still logged in".
-x Display the system shutdown entries and run level changes.
I am sorry, I am not a native speaker like yourself (judging from your
email address). To me "as of" meant logins starting from the given time
and later. It seems here it meant logins from the given time and older.
As for -x returning changes in runlevel as well you are right. I just
did a diff between two runs (on with and one without -x) and indeed both
show shutdown entries, but using -x gives lines like "runlevel (to lvl
2) 2.6.8-2-386 Sun Jul 17 11:58 - 14:49 (5+02:51)" as well.
Thanks for making me see. I learn every day... `;-)
