[chrony-users] chrony-3.0-pre1 released

[ Thread Index | Date Index | More chrony.tuxfamily.org/chrony-users Archives ]

The first prerelease for chrony-3.0 is now available. There are
several new features that can significantly improve accuracy and
stability of synchronisation. Hardware timestamping on Linux combined
with the interleaved mode, or a hardware NTP server, allows for
sub-microsecond accuracy on local networks.
