<p>
The number of seconds of estimated in-flight lag time of message data. When you create dataset contents using
message data from a specified timeframe, some message data might still be in flight when processing begins, and
so do not arrive in time to be processed. Use this field to make allowances for the in flight time of your
message data, so that data not processed from a previous timeframe is included with the next timeframe.
Otherwise, missed message data would be excluded from processing during the next timeframe too, because its
timestamp places it within the previous timeframe.
