125 as the fastest, highest-precision measurement of the passage of time
136 TSC again, it might appear that "time went backwards". This loss of
175 "time going backwards" problems might once again occur for those
178 machine to a 1.5GHz machine, attempts by an OS/app to measure time
259 was properly initialized to zero on all processors at boot-time
269 TSC as a usable clocksource; while time will not go backwards, it may
270 not track wallclock time well enough to avoid certain time-sensitive
293 of time. This sophisticated algorithm obtains information from a memory
303 to obtain key time values similar to the information accessible
309 anytime the domain is restored/migrated (thus changing key time values);
321 Finally, Xen provides additional time-related information via
332 and also much faster than nearly all OS-provided time mechanisms.
