//    Mask  	Description
//    d 	Day of the month as digits; no leading zero for single-digit days.
//    dd 	Day of the month as digits; leading zero for single-digit days.
//    ddd 	Day of the week as a three-letter abbreviation.
//    dddd 	Day of the week as its full name.
//    m 	Month as digits; no leading zero for single-digit months.
//    mm 	Month as digits; leading zero for single-digit months.
//    mmm 	Month as a three-letter abbreviation.
//    mmmm 	Month as its full name.
//    yy 	Year as last two digits; leading zero for years less than 10.
//    yyyy 	Year represented by four digits.
//    h 	Hours; no leading zero for single-digit hours (12-hour clock).
//    hh 	Hours; leading zero for single-digit hours (12-hour clock).
//    H 	Hours; no leading zero for single-digit hours (24-hour clock).
//    HH 	Hours; leading zero for single-digit hours (24-hour clock).
//    M 	Minutes; no leading zero for single-digit minutes.
//    		Uppercase M unlike CF timeFormat's m to avoid conflict with months.
//    MM 	Minutes; leading zero for single-digit minutes.
//    		Uppercase MM unlike CF timeFormat's mm to avoid conflict with months.
//    s 	Seconds; no leading zero for single-digit seconds.
//    ss 	Seconds; leading zero for single-digit seconds.
//    l or L 	Milliseconds. l gives 3 digits. L gives 2 digits.
//    t 	Lowercase, single-character time marker string: a or p.
//    		No equivalent in CF.
//    tt 	Lowercase, two-character time marker string: am or pm.
//    		No equivalent in CF.
//    T 	Uppercase, single-character time marker string: A or P.
//    		Uppercase T unlike CF's t to allow for user-specified casing.
//    TT 	Uppercase, two-character time marker string: AM or PM.
//    		Uppercase TT unlike CF's tt to allow for user-specified casing.
//    Z 	US timezone abbreviation, e.g. EST or MDT. With non-US timezones or in the Opera browser, the GMT/UTC offset is returned, e.g. GMT-0500
//    		No equivalent in CF.
//    o 	GMT/UTC timezone offset, e.g. -0500 or +0230.
//    		No equivalent in CF.
//    S 	The date's ordinal suffix (st, nd, rd, or th). Works well with d.
//    		No equivalent in CF.
//    UTC: 	Must be the first four characters of the mask. Converts the date from local time to UTC/GMT/Zulu time before applying the mask. The "UTC:" prefix is removed.
//    		No equivalent in CF.
//    '…' or "…" 	Literal character sequence. Surrounding quotes are removed.
//         		No equivalent in CF.
//   	
//   
//    And here are the named masks provided by default (you can easily change these or add your own):

//    default 		ddd mmm dd yyyy HH:MM:ss 	 Sat Jun 09 2007 17:46:21
//    shortDate 	m/d/yy 	   			 6/9/07
//    mediumDate 	mmm d, yyyy			 Jun 9, 2007
//    longDate 		mmmm d, yyyy 			 June 9, 2007
//    fullDate 		dddd, mmmm d, yyyy 		 Saturday, June 9, 2007
//    shortTime 	h:MM TT 			 5:46 PM
//    mediumTime 	h:MM:ss TT 			 5:46:21 PM
//    longTime 		h:MM:ss TT Z 			 5:46:21 PM EST
//    isoDate 		yyyy-mm-dd 			 2007-06-09
//    isoTime 		HH:MM:ss 			 17:46:21
//    isoDateTime 	yyyy-mm-dd'T'HH:MM:ss 		 2007-06-09T17:46:21
//    isoUtcDateTime 	UTC:yyyy-mm-dd'T'HH:MM:ss'Z' 	 2007-06-09T22:46:21Z
//   
//    A couple issues:
//   
//        * In the unlikely event that there is ambiguity in the meaning of your mask (e.g., m followed by mm, with no separating characters), put a pair of empty quotes between your metasequences. The quotes will be removed automatically.
//        * If you need to include literal quotes in your mask, the following rules apply:
//              o Unpaired quotes do not need special handling.
//              o To include literal quotes inside masks which contain any other quote marks of the same type, you need to enclose them with the alternative quote type (i.e., double quotes for single quotes, and vice versa).
//                E.g., date.format('h "o\'clock, y\'all!"') returns "6 o'clock, y'all". This can get a little hairy, perhaps, but I doubt people will really run into it that often.
//                The previous example can also be written as date.format("h") + "o'clock, y'all!".
