The main reason for my suspicion is a case of old faulty
GPS hardware which reported last years leap second twice.
This led to the question how to detect such errors.
But also in general it would be interesting to see how the
hosts controlled by ntp behave with respect to an independent
clock. If

Somehow using an HP 5071 to discipline the time without kernel support
seems bizarre, but it could be done in a spacecraft with only
intermittent contact with Earth. At the default rate of dispersion
increase of 15 us/s and distance threshold at the default 1.5 s, the
client will coast

Hi,
I'm trying to replace the linux/unix system clock by a special clock
maintained on a PCI card. The clock can be set, rate adjusted, etc., so
I have the equivalent for gettimeofday(), settimeofday(), adjtime(), etc.
Unfortunately, I'm confused by the number of different abstraction
levels
The normal method, and the cleanest, is to provide a reference clock
driver and let ntp keep the kernel clock synchronized to the card
timebase. If you are bound and determined to make your own code, the
place to start is in configure to specify your clock model and then
systime.c in libntp. Be
Hi
We purchased an EMC professional net as seen on www.gude.info last week,
and set it to test.
During the weekend - saturday evening 18.27 according to the syslog - it
synchronized with the (poorly recieved) Dcf77 signal and claimed the date to
be 27/3 2013...
I sendt it back to the seller

Patrick,
An external timebase has been implemented in two ways. The most
desireable is via the kernel and an appropriate shared memory device
driver. An alternative way is to used a driver such as the KSI/Odetics
TPRO refclock driver. There might even be a refclock driver for the old
