That's the default JSON format of an encoded date. You'll have to override some internal methods of Ext to have it another way.
Look for "Ext.JSON = new(function() {"
You'll need to patch these I think:
Code:
this.encodeDate = function(o) {
return '"' + o.getFullYear() + "-"
+ pad(o.getMonth() + 1) + "-"
+ pad(o.getDate()) + "T"
+ pad(o.getHours()) + ":"
+ pad(o.getMinutes()) + ":"
+ pad(o.getSeconds()) + '"';
};
isNative = function() {
var useNative = null;
return function() {
if (useNative === null) {
useNative = Ext.USE_NATIVE_JSON && window.JSON && JSON.toString() == '[object JSON]';
}
return useNative;
};
}(),
