Usage:Copy codeThe Code is as follows: var now = new date ();

Now. Format ("m/DD/YY ");
// Returns, e.g., 6/09/07

// Can also be used as a standalone Function
Dateformat (now, "dddd, Mmmm ds, yyyy, H: mm: ss tt ");
// Saturday, June 9th, 2007, 5:46:21

// You can use one of several named masks
Now. Format ("isodatetime ");
// 2007-06-09t17: 46: 21

//... Or add your own
Dateformat. Masks. hammertime = 'hh: Mm! "Can \'t touch this! "';
Now. Format ("hammertime ");
! Can't touch this!

// When using the standalone dateformat function,
// You can also provide the date as a string
Dateformat ("Jun 9 2007", "fulldate ");
// Saturday, June 9, 2007

// Note that if you don't include the mask argument,
// Dateformat. Masks. Default is used
Now. Format ();
// Sat Jun 09 2007 17:46:21

// And if you don't include the date argument,
// The current date and time is used
Dateformat ();
// Sat Jun 09 2007 17:46:22

// You can also skip the date argument (as long as your mask doesn't
// Contain any numbers), in which case the current date/time is used
Dateformat ("Longtime ");
// 5:46:22 est

// And finally, you can convert local time to UTC time. Either pass in
// True as an additional argument (no argument skipping allowed in this case ):
Dateformat (now, "Longtime", true );
Now. Format ("Longtime", true );
// Both lines return, e.g., 10:46:21 UTC

//... Or add the prefix "UTC:" to your mask.
Now. Format ("UTC: H: mm: ss tt z ");
// 10:46:21 UTC

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 cfTimeformat'S m to avoid conflict with months.
Mm	Minutes; leading zero for single-digit minutes. Uppercase mm unlike cfTimeformat'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.LGives 3 digits.LGives 2 digits.
T	Lowercase, single-character time marker string:AOrP. No equivalent in CF.
TT	Lowercase, two-character time marker string:AMOrPM. No equivalent in CF.
T	Uppercase, single-character time marker string:AOrP. Uppercase t unlike CF's t to allow for user-specified casing.
TT	Uppercase, two-character time marker string:AMOrPM. Uppercase TT unlike CF's TT to allow for user-specified casing.
Z	US timezone abbreviation, e.g.ESTOrMDT. 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.-0500Or+ 0230. No equivalent in CF.
S	The date's ordinal suffix (St,Nd,Rd, OrTh). Works wellD. No equivalent in CF.
'... ' Or "... "	Literal Character Sequence. surrounding quotes are removed. 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.
