public ProposedTimestamp propose()

Implements org.eclipse.jgit.util.time.MonotonicClock.propose.

Doc from org.eclipse.jgit.util.time.MonotonicClock.propose.

Obtain a timestamp close to "now".

Proposed times are close to "now", but may not yet be certainly in the past. This allows the calling thread to interleave other useful work while waiting for the clock instance to create an assurance it will never in the future propose a time earlier than the returned time.

A hypothetical implementation could read the local system clock (managed by NTP) and return that proposal, concurrently sending network messages to closely collaborating peers in the same cluster to also ensure their system clocks are ahead of this time. In such an implementation the org.eclipse.jgit.util.time.ProposedTimestamp#blockUntil(Duration) method would wait for replies from the peers indicating their own system clocks have moved past the proposed time.

Returns:ProposedTimestamp

a org.eclipse.jgit.util.time.ProposedTimestamp object.
