The following example shows how to interpret date and time patterns in the U.S. language environment. The given date and time is 2001-07-04 12:08:56 for the Pacific Time zone in the United States.
Date and Time pattern results
"YYYY. Mm.dd G ' at ' HH:mm:ss z ' 2001.07.04 AD at 12:08:56 PDT
"EEE, MMM D, ' yy" Wed, June 4, ' 01
"H:mm a" 12:08 PM
"HH ' o ' clock ' A, zzzz" O ' clock PM, Pacific Daylight Time
"K:mm A, z" 0:08 PM, PDT
"Yyyyy. MMMMM.DD GGG hh:mm aaa "02001.july.04 AD 12:08 PM
"EEE, D MMM yyyy HH:mm:ss Z" Wed, 4 June 2001 12:08:56-0700

"Yyyy-mm-dd ' T ' HH:mm:ss." Sssz "2001-07-04t12:08:56.235-0700
In ExtJS, formatting is not consistent with the above. The following can also be applied to Gwt-ext
Sample data:
' Wed 2007 15:05:01 GMT-0600 (Central Standard Time) '
Format character Output description
------ ---------- --------------------------------------------------------------
d The number of days in October, two digits, insufficient bit to fill "0"
D Wed The current week's abbreviation, three letters
J The number of days in October, do not fill "0"
L Wednesday the full spelling of the current week
S th English suffix for the ordinal number of days of the month, 2 characters (used with the format character "J")
W 31 days in the week (1~7)
Z Days of 91 years (0~365)
Number of weeks in 11 years, two digits (00~52)
F January the full spelling of the current month
M 01 current month, two digits, insufficient bit complement "0"
M the full spelling of the current month, three letters
N 1 The current month, do not fill "0"
T 31 total days of the current month
L 0 whether Leap year ("1" for leap Year, "0" for excepting)
Y 2007 4-digit number of the current year
Y 07 2-digit number of the current year
A PM lowercase "am" and "PM"
A PM "AM" and "PM" uppercase
G 3 12-hour system represents the current number of hours, does not complement the "0"
G 15 24-hour system represents the current number of hours, does not complement the "0"
H 03 12-hour system represents the current number of hours, insufficient bit to fill "0"
H 15 24-hour system represents the current number of hours, insufficient bit to fill "0"
I 05 min Digit complement "0" minutes
s 01 number of seconds with insufficient bit complement "0"
Number of O-0600 in hours and GMT difference
T CST Current system setting time zone
Z-21600 time zone offset in seconds (negative in the West, positive in the east)
Usage Examples: (Note that you must use the convert character "\" before the letter to output it as the letter itself rather than the format character):
var dt = new Date (' 1/10/2007 03:05:01 PM GMT-0600 ');
document.write (Dt.format (' y-m-d ')); 2007-01-10
document.write (Dt.format (' F J, Y, g:i a ')); January, 2007, 3:05 PM
document.write (Dt.format (' L, \\t\\he DS of F Y h:i:s A ')); Wednesday, the 10th of January 2007 03:05:01 PM
var mydate = new Date ();
Mydate.getyear (); Get Current year (2-bit)
Mydate.getfullyear (); Get full year (4-bit, 1970-????)

Mydate.getmilliseconds (); Get current number of milliseconds (0-999)
Mydate.tolocaledatestring (); Get Current date
var mytime=mydate.tolocaletimestring (); Get current time
Mydate.tolocalestring (); Get Date and time
