> I need to specify the event time when consuming pubsub data.
> {code:java}
> PCollection<PubsubMessage> pubsubMessages = pipeline.apply("Read Pub/Sub Data",
> PubsubIO.readMessagesWithAttributes()
> .withTimestampAttribute(options.getTimeAttribute())
> .fromSubscription(options.getInputSubscription()));
> {code}
> The only way to do this is to use the {color:#ff0000}withTimestampAttribute(){color} method.
> But if I use a timestamp in some other format, such as a 19-bit nanosecond, or if save the event time in the payload. The method won't work !
> So I had to extend the PubsubClient class and override the PubsubClient. extractTimestamp() method.
> I'am hoping to provide a way to pass in some implementation class that would allow to parse out timestamp from the current pubsub message.
