The consistent read_time for the given target_ids (omitted when the
target_ids are not at a consistent snapshot).
The stream is guaranteed to send a read_time with target_ids empty
whenever the entire stream reaches a new consistent snapshot. ADD,
CURRENT, and RESET messages are guaranteed to (eventually) result in a
new consistent snapshot (while NO_CHANGE and REMOVE messages are not).
For a given stream, read_time is guaranteed to be monotonically
increasing.
