JS Time format GMT format conversion

JavaScript Time Format Conversion Summary
1. Current system locale format (tolocaledatestring and tolocaletimestring)
Example: (new Date ()). toLocaleDateString () + "" + (new Date ()). toLocaleTimeString ()
Results: January 29, 2008 16:13:11
2. Ordinary strings (todatestring and toTimeString)
Example: (new Date ()). toDateString () + "" + (new Date ()). toTimeString ()
Results: Tue Jan 16:13:11 utc+0800
3. Greenwich Mean Time (togmtstring)
Example: (New Date ()). toGMTString ()
Results: Tue, Jan 08:13:11 UTC
4. Global Standard Time (toutcstring)
Example: (New Date ()). toUTCString ()
Results: Tue, Jan 08:13:11 UTC
5.Date Object String (toString)
Example: (New Date ()). ToString ()
Results: Tue Jan 16:13:11 utc+0800 2008
var today = new Date ();
document.write (today); In IE: Sun Mar 9 09:42:27 utc+0800 2008; in Firefox: Sun Mar 09:42:27 gmt+0800
var sentence = today.tostring ();
document.write (sentence);//In IE: Sun Mar 9 09:44:42 utc+0800 2008; in Firefox: Sun Mar, 09:44:42 gmt+0800
var GMT = today.togmtstring ();
document.write (GMT);//In IE Sun, 9 mar 01:46:38 UTC; In Firefox: Sun, Mar 01:46:38 GMT
var UTC = Today.toutcstring ();
document.write (UTC);//In IE Sun, 9 Mar 01:46:38 UTC; In Firefox: Sun, Mar 01:46:38gmt
