operations, which allow you to manage message acknowledgments in
bulk. That is, you can set the acknowledgment state of messages in
an existing subscription to the state captured by a snapshot.

expire_time |
google.protobuf.timestamp_pb2.Timestamp
The snapshot is guaranteed to exist up until this time. A newly-created snapshot expires no later than 7 days from the time of its creation. Its exact lifetime is determined at creation by the existing backlog in the source subscription. Specifically, the lifetime of the snapshot is 7 days - (age of oldest unacked message in the subscription).
For example, consider a subscription whose oldest unacked
message is 3 days old. If a snapshot is created from this
subscription, the snapshot -- which will always capture this
3-day-old backlog as long as the snapshot exists -- will
expire in 4 days. The service will refuse to create a
snapshot that would expire in less than 1 hour after
creation.
