The optional set time places the time and date of the plot either at the top or bottom of the left margin. The exact location is device dependent.
Syntax:
set time {<xoff>}{,<yoff>}
set notime
show time
Specifying constants <xoff> or <yoff> as optional offsets for the time will move the time <xoff> or <yoff> character screen coordinates. For example,
set time ,-3
will change only the y offset of the time, moving the title down by roughly the height of three characters.
