You forgot to show your timefmt setting, but it's highly doubtful this 
will do anywhere near what you think it does.  Try "show xrange" 
afterwards to see what you get, then read "help timefmt" again to see why.

This makes even less sense.  You can't really have the xtics starting 
point in a different time/date format than the xrange endpoints.

And it rather rarely makes sense to give the <increment> of a tic 
setting as a data string, since it's not an absolute time, but a 
difference.  Just give the number of seconds instead.

How do you think gnuplot is supposed to guess a new day started if your 
data (and the timefmt setting) don't contain information about days?

No.

The output format is independent.
