 `pattern` is a specially crafted attribute to support [Handlebars' template](https://handlebarsjs.com/guide/)
 with the following expressions:
 
-* `date 'format'` ; render date by its [moment format](https://momentjs.com/docs/#/displaying/format/)
+* `date 'format' tz='Timezone'` ; render date by its [moment format](https://momentjs.com/docs/#/displaying/format/). Default `tz` is UTC.
