+  const oldDate = new Date(date);
+  const newDate = new Date();
+  const stamp = oldDate.getTime();
+  if (!timeZone) return oldDate;
+  return (isNaN(timeZone) && !timeZone)
+    ? oldDate :
+    new Date(stamp + (newDate.getTimezoneOffset() * 60 * 1000) + (timeZone * 60 * 60 * 1000));
+}
+timeZoneConverter(new Date(1434701732*1000), 8)
+```
+
