* * Here are some standard date/time patterns that you might find helpful. They * are not part of the source of Date.js, but to use them you can simply copy this * block of code into any script that is included after Date.js and they will also become * globally available on the Date object. Feel free to add or remove patterns as needed in your code. *

Date.patterns = {
    ISO8601Long:"Y-m-d H:i:s",
    ISO8601Short:"Y-m-d",
    ShortDate: "n/j/Y",
    LongDate: "l, F d, Y",
    FullDateTime: "l, F d, Y g:i:s A",
    MonthDay: "F d",
    ShortTime: "g:i A",
    LongTime: "g:i:s A",
    SortableDateTime: "Y-m-d\\TH:i:s",
