Time Attributes
---------------
-### Event-time
+Flink supports different notions of *time* in streaming programs.
-* DataStream: Timestamps & WMs required, `.rowtime` (replace attribute or
extend schema)
-* TableSource: Timestamps & WMs & DefinedRowtimeAttribute
+- *Processing time* refers to the system time of the machine (also known
as "wall-clock time") that is executing the respective operation.
+- *Event time* is the time that each individual event occurred on its
producing device.
+- *Ingestion time* is the time that events enter Flink, internally, it is
treated similar to event time.
