fudge statement

&pagelevel(5)&pagelevel

Clocks can be configured via the server statement (see "server statement"). A further statement for configuring a clock is the fudge statement. The fudge statement must immediately follow the server statement that addresses the clock.


fudge 127.127.t.u[ stratum stratum]



t

identifies the type of clock.

u

is type-specific. The local system clock is specified with the pseudo IP address 127.127.1.0 and is the only clock possible in BS2000.

stratum

Integer that specifies the number of stations via which the local ntpd daemon can obtain a high-precision timestamp from an external clock. stratum can be significant in the configuration of the local system clock. stratum servers of stratum 1 have direct access to external time signals. Servers which receive their timestamps from stratum-1 servers are stratum-2 servers, and so on.

The value of stratum is the major criterion used by ntpd to select one server from several as the client. The local system clock is also a "server" for ntpd. The default value for its stratum is 5. By specifying a lower or higher value for its stratum in the fudge statement, you can thus assign the local system clock a higher or lower preference than the other servers.


Example (server mode with own clock)

# ntp.conf
#
#
server 127.127.1.0           #own clock
fudge  127.127.1.0 stratum 1
