<pre>
The time to execute the event. If you set
[execute_now][google.cloud.video.livestream.v1.Event.execute_now] to
`true`, then do not set this field in the `CreateEvent` request. In
this case, the server schedules the event and populates this field. If you
set [execute_now][google.cloud.video.livestream.v1.Event.execute_now] to
`false`, then you must set this field to at least 10 seconds in the future
or else the event can't be created.
</pre>

<code>.google.protobuf.Timestamp execution_time = 10;</code>

@return Whether the executionTime field is set.
