+Adding Timestamp - WithTimestamps
+---------------------------------
+
+Bounded sources (such as a file from TextIO) do not provide timestamps for
elements. If you need
+timestamps, you must add them to your PCollection’s elements.
+
+You can assign new timestamps to the elements of a PCollection by applying a
ParDo transform that
+outputs new elements with timestamps that you set.
+
+**Kata:** Please assign each element a timestamp based on the the
`Event.getDate()`.
Review comment:
Please to change the description to `Event.date`

Worklog Id: (was: 439098)
Time Spent: 11h 40m (was: 11.5h)
> Support for Kotlin-based Beam Katas
> -----------------------------------
>
> Key: BEAM-10027
> URL: https://issues.apache.org/jira/browse/BEAM-10027
> Project: Beam
> Issue Type: Improvement
> Components: katas
> Reporter: Rion Williams
> Assignee: Rion Williams
> Priority: P2
> Original Estimate: 8h
> Time Spent: 11h 40m
> Remaining Estimate: 0h
>
> Currently, there are a series of examples available demonstrating the use of
> Apache Beam with Kotlin. It would be nice to have support for the same Beam
> Katas that exist for Python, Go, and Java to also support Kotlin.
> The port itself shouldn't be that involved since it can still target the JVM,
> so it would likely just require the inclusion for Kotlin dependencies and a
> conversion for all of the existing Java examples.
