Name

ntptimeset

Synopsis

ntptimeset [-l] [-d]... [-v] [-s] [-c filename] [-u] [-S integer] 
[-V integer] [-t timeout] [-H] [-a key_id] [-e delay]

Description

Synchronizes the system clock in a manner similar to ntpdate, but in a way that attempts to compensate for current, possibly degraded, network conditions.

Options/Usage

-a

Enables secure authentication with the key specified by the given identifier.

-c

Specifies the location of the configuration file. Defaults to /etc/ntp.conf.

-d

Enables debugging output.

-e

Specifies the delay, in seconds, caused by authentication. Normally this value is negligible.

-H

Simulates poor network conditions by dropping a proportion of network packets.

-l

Enables logging to syslog.

-s

Sets the system clock. Otherwise, ntptimeset merely reports the clock’s offset.

-S

Specifies a minimum number of servers that must respond. Defaults to 3.

-t

Specifies time, in seconds, spent waiting for a server response. Defaults to 1.

-u

Uses an unprivileged client port.

Enables verbose output.

-V

Specifies a minimum number of servers that must respond with a valid time. Defaults to 1.
