How do you expect that to work for a time?  What time/date is '14' 
supposed to be?

If you're going to use time/date axes, your range will have to be in 
time/date format, too.  Gnuplot even, kinda-sorta, tells you so:

Note that "currently" setting.  That's how you're supposed to spell a 
setting of the xrange in this case.
