+## Using Timezone
+
+The optional 2nd parameter [LOCATION] argument is a string that references a timezone that is associated with the specified time value. If the time value has an explicit timezone or offset specified, it will take precedence over an explicit [LOCATION].

 ## Example: Using `time` to get Month Index
 
 The following example takes a UNIX timestamp---set as `utimestamp: "1489276800"` in a content's front matter---converts the timestamp (string) to an integer using the [`int` function][int], and then uses [`printf`][] to convert the `Month` property of `time` into an index.
