.It Dv CLOCK_REALTIME_PRECISE
.It Dv CLOCK_REALTIME_FAST
.It Dv CLOCK_REALTIME_COARSE
Increments as a wall clock should.
.It Dv CLOCK_MONOTONIC
.It Dv CLOCK_MONOTONIC_PRECISE
.It Dv CLOCK_MONOTONIC_FAST
.It Dv CLOCK_MONOTONIC_COARSE
Increments in SI seconds.
.It Dv CLOCK_UPTIME
.It Dv CLOCK_UPTIME_PRECISE
.It Dv CLOCK_UPTIME_FAST
.It Dv CLOCK_BOOTTIME
Starts at zero when the kernel boots and increments
monotonically in SI seconds while the machine is running.
.It Dv CLOCK_VIRTUAL

.Fa CLOCK_UPTIME_PRECISE
are used to get the most exact value as possible, at the expense of
execution time.
The clock IDs
.Fa CLOCK_REALTIME_COARSE ,
.Fa CLOCK_MONOTONIC_COARSE
are aliases of corresponding IDs with _FAST suffix for compatibility with other
systems.
Finally,
.Dv CLOCK_BOOTTIME
is an alias for
.Dv CLOCK_UPTIME
for compatibility with other systems.
