ackDeadlineSeconds property
The new ack deadline with respect to the time this request was sent to the Pub/Sub system.
For example, if the value is 10, the new ack deadline will expire 10
seconds after the ModifyAckDeadline call was made. Specifying zero might
immediately make the message available for delivery to another subscriber
client. This typically results in an increase in the rate of message
redeliveries (that is, duplicates). The minimum deadline you can specify
is 0 seconds. The maximum deadline you can specify in a single request is
600 seconds (10 minutes).
Required.
