# mongoc_client_session_advance_operation_time()

## Synopsis

    void
    mongoc_client_session_advance_operation_time (mongoc_client_session_t *session,
                                                  uint32_t timestamp,
                                                  uint32_t increment);

Advance the session’s operation time, expressed as a BSON Timestamp with timestamp and increment components. Has an effect only if the new operation time is greater than the session’s current operation time.

Use mongoc_client_session_advance_operation_time() and mongoc_client_session_advance_cluster_time() to copy the operationTime and clusterTime from another session, ensuring subsequent operations in this session are causally consistent with the last operation in the other session

## Parameters

- `session`: A mongoc_client_session_t.
- `timestamp`: The new operationTime’s timestamp component.
- `increment`: The new operationTime’s increment component.
