A summary of options is included below. -B PIXMAP, --background=PIXMAP Use the given pixmap as the clock background (size must be 64x64). -H COLOR, --hands-color=COLOR Draw the hands (hour, minute and second) in the specified color. -S COLOR, --second-hand-color Draw the second hand in the specified color -h, --help Show summary of options. --hour-hand-length=INT Draw the hour hand with the specified length of INT. --minute-hand-length=INT Draw the minute hand with the specified length of INT. --second-hand-length=INT Draw the second hand with the specified length of INT. --second-hand-width=INT Draw the minute hand with the specified width of INT. -s, --second-hand Don't display the second hand. -v, --version Show version of program. -w, --withdrawn Don't start up in a withdrawn (iconic) state.
