Other Options

Swatch Internet Time a.k.a. .Beat Time
@@@		= a decimal time concept introduced in 1998 and marketed by the Swatch corporation as an alternative, decimal measure of time. One of the goals was to simplify the way people in different time zones communicate about time, mostly by eliminating time zones altogether. Wikipedia: Swatch Internet Time
@@@.@	= also with first decimal place
@@@.@@	= and with second decimal place
Formatting
\n	 = Newline Character – Inserts a line break to wrap the output as you like.
“…”	 = To prevent a character from triggering its function encase it in “quotes”
LDATE = Use the default system configured Long Date format.
DATE   = Use the default system configured Short Date format.
TIME    = Use the default system configured Time format.
JD	= Julian Date - The Julian day is used in the Julian date (JD) system of time
               measurement for scientific use by the astronomy community. Julian date is
               recommended for astronomical use by the International Astronomical Union.
OD	= Ordinal Date (YYYY-DDD) - Using UTC/GMT/Zulu Time.
Od	= Ordinal Date (YYYY-DDD) - Using Local Time.
POSIX = Posix/Unix Time is the Number of Seconds that have elapsed since the
               Unix Epoch Date: 1970-01-01 00:00:00.
System Uptime 
Sd	= Number of Days system has been running.	(Not compatible with Sa)
Sa	= Total number of hours system has been running.	(Not compatible with Sd)
Sh	= Number of hours system has been running.	(Not compatible with Sa)
Sn	= Number of minutes system has been running.
Ss	= Number of seconds system has been running.
ST	= Short uptime displayed in h:mm:ss format.
Note: this function uses GetTickCount() on OS versions before Vista, so any uptime over 49.7 days will (wrap to 0) be inaccurate. Vista+ supports uptime to infinity though.
Note²: this format additionally supports advanced padding. "S__a" will pad with up to two spaces in case "hours" are less than 100. "S___dd" will pad with up to three spaces and additionally got a zero padded minimum size of two. eg. "   03" for a three hour uptime.

How to Use the PC Beep (.pcb) Sound Files
For Those Without Sound Cards

   For those that do not have sound (or just like these tones) T-Clock includes the option to use .pcb files to play a series of tones through the PC’s system speaker. The .pcb files are in a plain text format, and have a straight forward (duration, frequency) simple syntax. So they can be created or edited with any plain text editor (like Notepad).
   There is one demo.pcb file included in the Waves directory. Content of the file with line by line explanation is below: 
100, 400	Creates 100ms long 400Hz tone.
100, -1		100ms Pause between tones.
100, 500 	Creates 100ms long 500Hz tone.
100, -1		100ms Pause between tones.
100, 600 	Creates 100ms long 600Hz tone.
100, -1		100ms Pause between tones.
100, 500 	Creates 100ms long 500Hz tone.
100, -1		100ms Pause between tones.
100, 400 	Creates 100ms long 400Hz tone.
500, -1		500ms Pause at end of file for smoother looping.
   The first number (duration) is in milliseconds. It controls how long the tone or pause will be.
   The second number (frequency) is in hertz, and controls the pitch of the tone being played. Valid values are from 37 to 32767.
