clockspeed uses a hardware tick counter to compensate for a persistently
|
||
|
|
fast or slow system clock. Given a few time measurements from a reliable
|
||
|
|
source, it computes and then eliminates the clock skew.
|
||
|
|
|
||
|
|
sntpclock checks another system's NTP clock, and prints the results in a
|
||
|
|
format suitable for input to clockspeed. sntpclock is the simplest
|
||
|
|
available NTP/SNTP client.
|
||
|
|
|
||
|
|
taiclock and taiclockd form an even simpler alternative to SNTP. They
|
||
|
|
are suitable for precise time synchronization over a local area network,
|
||
|
|
without the hassles and potential security problems of an NTP server.
|
||
|
|
|
||
|
|
This version of clockspeed can use the Pentium RDTSC tick counter or the
|
||
|
|
Solaris gethrtime() nanosecond counter.
