I suspect you'll need the development version for that. You'll need at
least the new functionalities of strptime() and string expressions. I'm
not even sure it can be done with those:
> plot 'dat.txt' u 2 : ( $2 >= "20080524 22:00:00" && $2 <= "20080526
> 02:00:00" ? $1/10 : 1/0 ) t '' ps 0.4 pt 1 lt 2
Timefmt data and extended 'using' specifications don't work particularly
well together.

You understood that incorrectly. gnuplot handles dates and times in
seconds.

That's because xrange was specifically extended to allow that. Strings
in other contexts don't magically turn into numbers.
