-- | In a GetSampledRequests request, the @StartTime@ and @EndTime@ objects
-- specify the time range for which you want WAF to return a sample of web
-- requests.
--
-- You must specify the times in Coordinated Universal Time (UTC) format.
-- UTC format includes the special designator, @Z@. For example,
-- @\"2016-09-27T14:50Z\"@. You can specify any time range in the previous
-- three hours.
--
-- In a GetSampledRequests response, the @StartTime@ and @EndTime@ objects
-- specify the time range for which WAF actually returned a sample of web
-- requests. WAF gets the specified number of requests from among the first
-- 5,000 requests that your Amazon Web Services resource receives during
-- the specified time period. If your resource receives more than 5,000
-- requests during that period, WAF stops sampling after the 5,000th
-- request. In that case, @EndTime@ is the time that WAF received the
-- 5,000th request.
