Maybe ajji is talking bout the banlist of channel central (that is: its horizontal scrollbar) - missing parts of "set by, date, time" at the end.
banmask [tab] nick (user@host) date time
or, if you have not been present the time the ban was set:
banmask [tab] nick date time
having scrolled to the far right, often the part after [tab] is truncated nevertheless.... (using mirc 6.21, think this had been reported before)
