For 1 million invocations of  boost::posix_time::ptime ptm
(boost::posix_time::microsec_clock::local_time() );        // Get current
time
It takes about 1 sec.

However, gettimeofday takes about 300 ms.

gettimeofday takes about 300 ms.
// struct timeval tv;
// gettimeofday(&tv, NULL);

Any pointers on why it takes so long? I want to ensure that timestamp call
are not expensive. Any suggestion/recommendation?
