Macros
#define	TIMEX_MAX_STR_LEN (20)
	The maximum length of the string representation of a timex timestamp.

Functions
timex_t	timex_add (const timex_t a, const timex_t b)
	Adds two timestamps.

timex_t	timex_sub (const timex_t a, const timex_t b)
	Subtracts two timestamps.

timex_t	timex_set (uint32_t seconds, uint32_t microseconds)
	Initializes a timex timestamp.

int	timex_cmp (const timex_t a, const timex_t b)
	Compares two timex timestamps.

static void	timex_normalize (timex_t *time)
	Corrects timex structure so that microseconds < 1000000.

static int	timex_isnormalized (const timex_t *time)
	Tests a timex timestamp for normalization.

static uint64_t	timex_uint64 (const timex_t a)
	Converts a timex timestamp to a 64 bit value.

static timex_t	timex_from_uint64 (const uint64_t timestamp)
	Converts a 64 bit value of microseconds to a timex timestamp.

const char *	timex_to_str (timex_t t, char *timestamp)
	Converts a timex timestamp to a string.
