Macros
#define	Q(frac, fval)   ((1 << (frac)) * (fval))
#define	FRAC   10
#define	SHR_FP(val, frac)   (((coap_tick_t)((val) + (1 << ((frac) - 1)))) >> (frac))

Functions
void	coap_clock_init (void)
	Initializes the internal clock.
void	coap_ticks (coap_tick_t *t)
	Returns the current value of an internal tick counter.
coap_time_t	coap_ticks_to_rt (coap_tick_t t)
	Helper function that converts coap ticks to wallclock time.
uint64_t	coap_ticks_to_rt_us (coap_tick_t t)
	Helper function that converts coap ticks to POSIX wallclock time in us.
coap_tick_t	coap_ticks_from_rt_us (uint64_t t)
	Helper function that converts POSIX wallclock time in us to coap ticks.

Variables
