// Insights queries.

// TimeLayout defines the format by showing how the Go reference time of
//
//	Mon Jan 2 15:04:05 -0700 MST 2006
//
// would be formatted if it were the value. TimeLayout can be used with
// time.Parse to parse timestamp fields, such as @timestamp and @ingestionTime,
// which are returned within CloudWatch Logs Insights query results.
