Currently there is no operations around event time.
The closest we have offered in Pulsar is seeking (or rest-cursor) by
publish time. Although the API is still a best-effort by doing binary
lookup.
That reminds me of another question I meant to ask. When a message is
published, is the publish time assigned by the client or by the broker?
And does Pulsar do anything to ensure that publish time is monotonically
increasing on a given topic?
Since timestamps are at millisecond resolution, and you have two clients
or two brokers with clocks that aren't properly synchronised, ISTM you
could get values which aren't monotonic.
