  64  * Here are some standard date/time patterns that you might find helpful.  They
  65  * are not part of the source of Date.js, but to use them you can simply copy this
  66  * block of code into any script that is included after Date.js and they will also become
  67  * globally available on the Date object.  Feel free to add or remove patterns as needed in your code.
  68  * &lt;pre&gt;&lt;code&gt;
  69 Date.patterns = {
  70     ISO8601Long:&quot;Y-m-d H:i:s&quot;,

  92  * Most of the date-formatting functions below are the excellent work of Baron Schwartz.
  93  * They generate precompiled functions from date formats instead of parsing and
  94  * processing the pattern every time you format a date.  These functions are available
