Convert to C/C++?

I am wondering if someone who knows the implemention of python's time
could help converting this to c/c++....

		nanoseconds = int(time.time() * 1e9)
		# 0x01b21dd213814000 is the number of 100-ns intervals between the
		# UUID epoch 1582-10-15 00:00:00 and the Unix epoch 1970-01-01
00:00:00.
		self.timestamp = int(nanoseconds/100) + 0x01b21dd213814000L
		self.clock_seq = random.randrange(1<<14L) # instead of stable
storage
		self.time_low = self.timestamp & 0xffffffffL
		self.time_mid = (self.timestamp >> 32L) & 0xffffL
		self.time_hi_version = (self.timestamp >> 48L) & 0x0fffL
		self.clock_seq_low = self.clock_seq & 0xffL
		self.clock_seq_hi_variant = (self.clock_seq >> 8L) & 0x3fL
		#print 'timestamp ', self.timestamp, self.time_low, self.time_mid,
self.time_hi_version
		#print 'clock_seq ', self.clock_seq, self.clock_seq_low,
self.clock_seq_hi_variant

vs unix gettimeofday....

int gettimeofday(struct timeval *tp, struct timezone *tzp);

struct timeval {
   long tv_sec;         /* seconds since Jan. 1, 1970 */
   long tv_usec;        /* and microseconds */
};

struct timezone {
   int tz_minuteswest; /* of Greenwich */
   int tz_dsttime;     /* type of dst correction to apply */
};
