48 The ffclock implements a feed-forward paradigm and decouples the timestamping
53 The feed-forward approach has demonstrated better performance and higher

65 feed-forward counter maintained by the kernel.
71 system calls allow the caller to get and set the kernel's feed-forward clock
75 system call should be invoked by a single instance of a feed-forward
79 system call can be called by any process to retrieve the feed-forward clock
82 The feed-forward approach does not require that the clock estimates be retrieved
89 must be used when the feed-forward synchronisation daemon is not running
114 Only the super-user may set the feed-forward clock estimates.
128 A user other than the super-user attempted to set the feed-forward clock
132 The feed-forward paradigm enables the definition of specialised clock functions.
