Returns whether there exists an event in the event log with an com.digitalasset.canton.participant.LocalOffset of at most
localOffsetwhose timestamp is at leasttimestamp.Returns whether there exists an event in the event log with an com.digitalasset.canton.participant.LocalOffset of at most
localOffsetwhose timestamp is at leasttimestamp.In an event logs where timestamps need not increase with offsets, this can be used to check that whether there are events with lower offsets and larger timestamps.
