-- | This structure includes the @Timezone@ parameter, which you can use to
-- specify your time zone so that the labels that are associated with
-- returned metrics display the correct time for your time zone.
--
-- The @Timezone@ value affects a label only if you have a time-based
-- dynamic expression in the label. For more information about dynamic
-- expressions in labels, see
-- <https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/graph-dynamic-labels.html Using Dynamic Labels>.
