what's the origin of this file?

is it copied from somewhere?

Kind of.  It uses the same names and sometimes the same code for functions in
the Google Closure Library.  I could probably put them in a 'util' namespace.

+goog.object = {};
+goog.object.forEach = function (obj, f, optObj) {
+    "use strict";
+    var key;
+    for (key in obj) {
+        if (obj.hasOwnProperty(key)) {
+            f.call(optObj, obj[key], key, obj);
+        }
+    }
+};
+
+goog.array = {};
+goog.array.forEach = function (arr, f, env) {
+    "use strict";
+
+    f = f.bind(env);
+
+    var len = arr.length,
+        i = 0;
+    for (i = 0; i < len; i += 1) {
+        f(arr[i]);
+    }
+};
+
+goog.array.filter = function (arr, f) {
+    "use strict";
+    return arr.filter(f);
+};
+
+goog.array.map = function (arr, f) {
+    "use strict";
+    return arr.map(f);
+};
+
+goog.time = {};
+goog.time.millisToString = function (timeMillis) {
+    "use strict";
+    function pad(num) {
+        num = num.toString();
+        if (num.length < 2) {
+            return "0" + num;
+        }
+        return num;
+    }
+
+    var date = new Date(timeMillis);
+    return pad(date.getUTCHours()) + ':' + pad(date.getUTCMinutes()) + ':' +
+        pad(date.getUTCSeconds()) + ' ' + pad((date.getMilliseconds()) % 1000);
+};
