However, on the other hand, due to historical reasons, no matter which language the Date is in, there are many letters characterizing its format variables.

Time Zone
O The time difference from Greenwich Mean Time. For example, 1030
P with a colon is the time difference from Greenwich Mean Time. For example -08:00
T is the abbreviation of the time zone of the machine running the current code. For example, EST, MDT, PDT
c ISO8601 date representation (note that if the second has a decimal part, it must be at least 1 digit, and there is no limit to more. See www.w3.org/TR/NOTE-datetiem for more information .

The above are the format symbols of Date. Pay special attention when using them, because sometimes when we customize the format, we will encounter letters in some words that are consistent with the format symbols. situation. Of course, what we need to output at this time is the word rather than the content represented by a certain Date, so we must use escape characters at this time.For example:

var dt = new Date('1/10/2007 03:05:01 PM GMT-0600');
document.write(dt.format('Y-m-d')) ; (dt.format('l, \t\he jS \of F Y h:i:s A')); // Wednesday, the 10th of January 2007 03:05:01 PM

The following is given Create a date-style object. This is available in the API and is very easy to use. Although it is not part of Date itself. However, flexible application will bring great convenience to program writing.
