#define COAP_TICKS_PER_SECOND ((coap_tick_t)(1000U)) 
Use ms resolution on POSIX systems.

typedef int64_t coap_tick_diff_t 
This data type is used to represent the difference between two clock_tick_t values.
This data type must have the same size in memory as coap_tick_t to allow wrapping.
Definition at line 139 of file coap_time.h.
typedef uint64_t coap_tick_t 
This data type represents internal timer ticks with COAP_TICKS_PER_SECOND resolution.
Definition at line 127 of file coap_time.h.
typedef time_t coap_time_t 
CoAP time in seconds since epoch.
Definition at line 132 of file coap_time.h.
void coap_clock_init  (  void  ) 
Initializes the internal clock.
void coap_ticks  (  coap_tick_t *  t  ) 
Sets t
to the internal time with COAP_TICKS_PER_SECOND resolution.
coap_tick_t coap_ticks_from_rt_us  (  uint64_t  t  ) 
Helper function that converts POSIX wallclock time in us to coap ticks.
t  POSIX time is us 
coap_time_t coap_ticks_to_rt  (  coap_tick_t  t  ) 
Helper function that converts coap ticks to wallclock time.
On POSIX, this function returns the number of seconds since the epoch. On other systems, it may be the calculated number of seconds since last reboot or so.
t  Internal system ticks. 
uint64_t coap_ticks_to_rt_us  (  coap_tick_t  t  ) 
Helper function that converts coap ticks to POSIX wallclock time in us.
t  Internal system ticks. 
COAP_STATIC_INLINE int coap_time_le  (  coap_tick_t  a, 
coap_tick_t  b  
) 
Returns 1
if and only if a
is less than or equal b
where less is defined on a signed data type.
Definition at line 198 of file coap_time.h.
COAP_STATIC_INLINE int coap_time_lt  (  coap_tick_t  a, 
coap_tick_t  b  
) 
Returns 1
if and only if a
is less than b
where less is defined on a signed data type.
