" H" is converted to Hour

I am trying to script a dynamic stamp.

While I am adding menu in Javascript , wherever I use alphaber -"H" it is converted to Hour. How can I resolve this.

var DateDlg = {  result: "cancel",  DoDialog: function () { return app.execDialog(this); },
              strDefFmt: "mm-dd-yyyy",
              strFmt: "SCHEDULED ",
              vDate: new Date, strDate: "",
