Date object Formatting Function Code _ time Date

Date object formatting method. For more information, see. The Code is as follows:

/*
* Date Format 1.2.3

*
* Includes enhancements by Scott Trenda
* And Kris Kowal
*
* Accepts a date, a mask, or a date and a mask.
* Returns a formatted version of the given date.
* The date defaults to the current date/time.
* The mask defaults to dateFormat. masks. default.

Usage:

The 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.
