Assigns timestamps to all the elements of a collection.
## Examples
-See [BEAM-7389](https://issues.apache.org/jira/browse/BEAM-7389) for updates.
-## Related transforms

}}/documentation/transforms/python/elementwise/reify) converts between explicit
and implicit forms of Beam values.

+In the following examples, we create a pipeline with a `PCollection` and
attach a timestamp value to each of its elements.
+Timestamps are especially useful on streaming pipelines where windowing and
late data play a more important role.
+
+### Example 1: Timestamp by event time
+
+Often times, the elements themselves already contain a timestamp field that
can be used.
+`beam.window.TimestampedValue` will take a value and a timestamp in the form
of seconds, where a unix timestamp can be used.
Review comment:
"`beam.window.TimestampedValue` takes a value and a Unix timestamp in the
form of seconds."
^is this sentence still accurate? Else try shortening the sentence:
"`beam.window.TimestampedValue` takes a value and a timestamp in the form of
seconds."
and you have a comment after this section on converting to Unix timestamps.
