The command `set timestamp` places the time and date of the plot in the left
margin.
Syntax:
set timestamp {"<format>"} {top|bottom} {{no}rotate}
{<xoff>}{,<yoff>} {"<font>"}
set notimestamp
show timestamp
The format string allows you to choose the format used to write the date and
time. Its default value is what asctime() uses: "%a %b %d %H:%M:%S %Y"
(weekday, month name, day of the month, hours, minutes, seconds, four-digit
year). With `top` or `bottom` you can place the timestamp at the top or
bottom of the left margin (default: bottom). `rotate` (Note:rotate ) lets
you write the timestamp vertically, if your terminal supports vertical
text. The constants <xoff> and <off> are offsets from the default position
given in character screen coordinates. <font> is used to specify the font
with which the time is to be written.
The abbreviation `time` may be used in place of `timestamp`.
Example:
set timestamp "%d/%m/%y %H:%M" 80,-2 "Helvetica"
See `set timefmt` (Note:timefmt ) for more information about time format
strings.
