NCLHELP.HLB  —  set  dtss
    set [node node-id] dtss ...

    Modifies the attributes for the dtss entity.  The modifiable
    attributes and their data types [in brackets] are:

    advertisement interval [relative-time]
    check interval [relative-time]
    courier role [role]
    error tolerance [relative-time]
    global directory [full-name]
    lan timeout [relative-time]
    maximum inaccuracy [relative-time]
    query attempts [integer]
    servers required [integer]
    synchronization hold down [relative-time]
    wan timeout [relative-time]

    Example:

    set dtss servers required 3

1  –  advertisement_interval 

    Default: 0-01:30:00.000    Value: 0-00:00:30.000-99-99:99:99.999

    Specifies the amount of time between a server's advertisement
    broadcasts.

2  –  check_interval 

    Default: 0-01:30:00.00     Value: 0-00:00:30.000-99-99:99:99.999

    Specifies the amount of time between checks for faulty servers.
    Applicable only to servers that have external time-providers.

3  –  courier_role 

    Specifies a server's interaction with the set of global servers.

    backup courier   The local server becomes a courier if none are
                     available on the LAN.

    courier          The local server synchronizes with the global set
                     of servers.

    noncourier       The local server does not routinely synchronize
                     with the global set of servers.  This is the
                     default.

4  –  error_tolerance 

    Default: 0-00:10:00.000    Value: 0-00:00:00.500-99-99:99:99.999

    Specifies the maximum separation allowed between the local clock
    and the computed time before synchronizations become abrupt
    rather than gradual (monotonic).

5  –  global_directory 

    Specifies the full name of the DECdns directory that contains the
    list of DECdts servers that belong to the global set.

6  –  lan_timeout 

    Default: 0-00:00:02.000    Value: 0-00:00:01.000-0-00:05:00.000

    Specifies the amount of time the node waits for a response
    to a synchronization request before sending another request
    or declaring a server to be unavailable. The node sends
    three requests before declaring a non-responding server to be
    unavailable.

7  –  maximum_inaccuracy 

    Default: 0-00:01:40.00     Value: 0-00:00:00.0 - 99 99:99:99.99

    Specifies the inaccuracy limit for the node. When the node exceeds
    the maximum inaccuracy setting, it attempts to synchronize.

8  –  query_attempts 

    Default: 3                 Value: 1-10

    Specifies the number of attempts that a node makes to contact a
    server before the node considers the server unavailable.

9  –  servers_required 

    Default: 3 (servers)       Value: 1-32
             1 (clerks)

    Specifies the minimum number of servers the specified node must
    successfully query for time values before it can synchronize.

10  –  synchronization_hold_down 

    Default: 0-00:10:00.0(Clerks)  Value: 0-00:00:30.0- 01 00:00:00.00
             0-00:02.00.0-(Servers)

    Specifies the interval a node must wait to synchronize. Also
    specifies synchronization frequency when a node reaches the value
    specified by the maximum inaccuracy characteristic.

11  –  wan_timeout 

    Default: 0-00:00:15.000    Value: 0-00:00:01.000-0-00:10:00.000

    Specifies the amount of time the node waits for a response to a
    WAN synchronization request before sending another request and
    declaring a global server to be unavailable. The node sends three
    requests before declaring a non-responding global server to be
    unavailable.
