Typedefs
typedef uint64_t	dispatch_time_t
	An somewhat abstract representation of time; where zero means "now" and DISPATCH_TIME_FOREVER means "infinity" and every value in between is an opaque encoding.
Functions
dispatch_time_t	dispatch_time (dispatch_time_t when, int64_t delta)
	Create dispatch_time_t relative to the default clock or modify an existing dispatch_time_t.
dispatch_time_t	dispatch_walltime (const struct timespec *when, int64_t delta)
	Create a dispatch_time_t using the wall clock.
