**-U**\ [*label*\ ][**+c**\ ][**+j**\ *just*\ ][**+o**\ *dx*/*dy*\ ]
    Draw the GMT Unix System time stamp on the plot.
    By appending **+j**\ *just* and/or **+o**\ *dx/dy*, the
    user may specify the justification of the stamp and where the stamp
    should fall on the page relative to lower left corner of the plot.
    For example, +jBL+o0/0 will align the lower left corner of the time
    stamp with the bottom left corner of the plot [BL]. Optionally, append a
    *label*, or give **+c** which will plot the command string. The GMT
    parameters :ref:`MAP_LOGO <MAP_LOGO>`, :ref:`MAP_LOGO_POS <MAP_LOGO_POS>`, and
    :ref:`FORMAT_TIME_STAMP <FORMAT_TIME_STAMP>` can affect the appearance; see the
    :doc:`gmt.conf` man page for details. The time string will be in the
    locale set by the environment variable **TZ** (generally local time).
