As described in the [timestamps and watermark handling]({{ site.baseurl }}/apis/streaming/event_timestamps_watermarks.html) page,
Flink provides abstractions that allow the programmer to assign her own timestamps and emit her own watermarks. More specifically,
she can do so by implementing one of the `AssignerWithPeriodicWatermarks` and `AssignerWithPunctuatedWatermarks` interfaces, depending
on her use-case. In a nutshell, the first will emit watermarks periodically, while the second does so based on some property of
Flink provides abstractions that allow the programmer to assign their own timestamps and emit their own watermarks. More specifically,
one can do so by implementing one of the `AssignerWithPeriodicWatermarks` and `AssignerWithPunctuatedWatermarks` interfaces, depending
on their use-case. In a nutshell, the first will emit watermarks periodically, while the second does so based on some property of
the incoming records, e.g. whenever a special element is encountered in the stream.

In order to further ease the programming effort for such tasks, Flink comes with some pre-implemented timestamp assigners.
