o  clock settings

    Specifies the number of times that the node clock has been set
    nonmonotonically (abruptly).

 o  creation time

    Specifies the time at which the DECdts entity was created and the
    counters were initialized.

 o  different epochs detected

    Specifies the number of times that the node received time response
    messages from servers or clerks that had epoch numbers different
    from its own.

 o  disable directives completed

    Specifies the number of times that DECdts has been disabled.

 o  enable directives completed

    Specifies the number of times that DECdts has been enabled.

 o  epoch changes completed

    Specifies the number of times that the server's epoch has changed.

 o  insufficient resources detected

    Specifies the number of times that the node has been unable to
    allocate virtual memory.

 o  invalid messages detected

    Specifies the number of times that the local node failed to
    process a received message that had an unknown message type or
    incorrect length.

 o  local times not intersecting

    Specifies the number of times that the node's time interval failed
    to intersect with the computed interval of the servers.

 o  no global servers detected

    Specifies the number of times that the courier server could not
    contact any global servers.

 o  protocol mismatches detected

    Specifies the number of times that the local node failed to
    process a received message containing an incompatible protocol
    version.

 o  server times not intersecting

    Specifies the number of times that a server has detected faulty
    servers (other than itself).

 o  servers not responding

    Specifies the number of times that the courier server could not
    contact a specific global server.

 o  synchronizations completed

    Specifies the number of times that the node has successfully
    synchronized.

 o  system errors detected

    Specifies the number of times a DECdts operation has detected a
    system error.

 o  time provider failures detected

    Specifies the number of times that the external time-provider
    signaled a failure or the node was unable to access the time-
    provider.

 o  time representation mismatches detected

    Specifies the number of times that the local node failed to
    process a received message containing an incompatible timestamp
    format.

 o  too few servers detected

    Specifies the number of times that a node failed to synchronize
    because it could not contact the required minimum number of
    servers.

 o  too many servers detected

    Specifies the number of times that the responses to a
    synchronization request overflowed the assigned system buffer.

 o  updates initiated

    Specifies the number of times that a server has attempted to
    update its clock.
