		* skin			Must be one of these: 'swissRail' (default skin), 'chunkySwiss', 'chunkySwissOnBlack', 'fancy', 'machine', 'simonbaird_com', 'classic', 'modern', 'simple', 'securephp', 'Tes2', 'Lev', 'Sand', 'Sun', 'Tor', 'Cold', 'Babosa', 'Tumb', 'Stone', 'Disc', 'watermelon' or 'mister'.
		* 				If the Advanced extension is activated, there is also 'minimal' available.
		* radius		A number to define the clock radius. Do not add 'px' or any other measure descriptor.
		* noseconds		Set to 'true' or 1 or without value to hide the second hand.
		* gmtoffset		A number to define a timezone relative the Greenwhich Mean Time. Do not set this parameter to default to local time.
		* showdigital	Set to 'true' or 1 or 'digital12' or without value to show the time in 12h digital format (with am/pm) too
		* fontcolor		Set to a color value to change the digital time color, digitalcolor for backward compatibility
		* scale			Must be one of these: 'linear' (default scale), 'logClock' or 'logClockRev'. Linear is our normal clock scale, the other two show a logarithmic time scale
		* subtext		Optional text, centered below the clock
		* align			Sets floating of the clock: 'left', 'right' or 'center'
