Copy Code code as follows:
/**
* An extension to date that converts date to a string of the specified format
* Month (M), Day (d), 12 hours (h), 24 hours (h), minutes (m), seconds (s), Week (E), quarter (q) can be 1-2 placeholders
* Year (Y) can be 1-4 placeholders, milliseconds (S) can only use 1 placeholders (1-3-digit digits)
* Eg:
* (New Date ()). Pattern ("Yyyy-mm-dd hh:mm:ss. S ") ==> 2006-07-02 08:09:04.423
* (New Date ()). Pattern ("Yyyy-mm-dd E HH:mm:ss") ==> 2009-03-10 II 20:09:04
* (New Date ()). Pattern ("Yyyy-mm-dd EE hh:mm:ss") ==> 2009-03-10 Tuesday 08:09:04
* (New Date ()). Pattern ("Yyyy-mm-dd EEE hh:mm:ss") ==> 2009-03-10 Tuesday 08:09:04
* (New Date ()). Pattern ("yyyy-m-d h:m:s.s") ==> 2006-7-2 8:9:4.18
