The high resolution timer -** strategy is (probably) best on all systems where the timer have -** a resolution higher or equal to gettimeofday (or what's implemented -** is sys_gettimeofday()). The actual resolution is the interesting thing, -** not the unit's thats used (i.e. on VxWorks, nanoseconds can be -** retrieved in terms of units, but the actual resolution is the same as -** for the clock ticks). -** If the systems best timer routine is kernel ticks returned from -** sys_times(), and the actual resolution of sys_gettimeofday() is -** better (like most unixes that does not have any realtime extensions), -** another strategy is used. The tolerant gettimeofday() corrects -** the value with respect to uptime (sys_times() return value) and checks -** for correction both when delivering timeticks and delivering nowtime. -** this strategy is slower, but accurate on systems without better timer -** routines. The kernel tick resolution is not enough to implement -** a gethrtime routine. On Linux and other non solaris unix-boxes the second -** strategy is used, on all other platforms we use the first. -** -** The following is expected (from sys.[ch] and erl_*_sys.h): -** -** 64 bit integers.

More could be added of course -** If the clock-rate is constant (i.e. 1 ms) one can define -** SYS_CLOCK_RESOLUTION (to 1), -** which makes erts_deliver_time/erts_time_remaining a bit faster. -** -** if HAVE_GETHRTIME is defined: -** sys_gethrtime() will return a SysHrTime (long long) representing -** nanoseconds, sys_init_hrtime() will do any initialization. -** else -** a long (64bit) integer type called Sint64 should be defined. -** -** sys_times() will return clock_ticks since start and -** fill in a SysTimes structure (struct tms).
