编译错误

#include "Poco/Timestamp.h"
#include<iostream>
#include <ctime>
using Poco::Timestamp;
int main(int argc,char** argv)
{
   Timestamp Now; // the current date and time
   std::time_t t1 = Now.epochTime(); // convert to time_t ...
   Timestamp ts1(Timestamp::fromEpochTime(t1)); // ... and back again
   for (int i = 0; i < 100000; ++i) ; // wait a bit
   Timestamp::TimeDiff diff = Now.elapsed(); // how long did it take?
   Timestamp start(Now); // save start time
   Now.update(); // update with current
   time
   diff = Now - start; // again,how long?
   return 0;
 }
