 An option represents a storage location for any value of a specified type.
 Options are mutable.
 An option can hold different values during its lifetime.
 
 Below is a list of built-in options currently implemented in the Flux language:
 
-- now
-- task
-- location
+- [now](#now)

 The `location` option sets the default time zone of all times in the script.
 The location maps the UTC offset in use at that location for a given time.
-The default value is set using the time zone of the running process.
+The default value is [`timezone.utc`](/flux/v0.x/stdlib/timezone/#constants).
 
 ```js
-option location = fixedZone(offset:-5h) // Set timezone to be 5 hours west of UTC.
