How to fix leap second sleep issue without reboot

I found that after the latest leap second insertion (2016-12-31 23:59:60), our CentOS7 application that has worker threads sleeping for 1 second between jobs, started to wake the sleeping threads immediately instead of in a second. In general, all sleeps are awake 1 second ahead of expected wake time.

The simplest and working solution is to reboot the box. But that is not desirable in our case. Is there a way to fix this without rebooting?

PS. For reference, here's a simple program in C++ that reproduces the issue.

#include <boost/date_time.hpp>
#include <boost/thread.hpp>
#include <iostream>

using namespace std;


// this has to be run in a thread to be able to detect the issue
void check_thread()
{
    size_t expected_delay = 1000;
    cout << "Expected delay: " << expected_delay << " ms" << endl;
    boost::posix_time::ptime t1 = boost::posix_time::microsec_clock::universal_time();
    boost::this_thread::sleep(boost::posix_time::milliseconds(1000));
    boost::posix_time::ptime t2 = boost::posix_time::microsec_clock::universal_time();
    size_t actual_delay = (t2 - t1).total_milliseconds();
    cout << "Actual delay: " << actual_delay << " ms" << endl;
    if (abs(expected_delay - actual_delay) > 900) {
        cout << "Too big delay difference: " << (expected_delay - actual_delay) << endl;
        cout << "Possible leap second issue" << endl;
    }
    else {
        cout << "No issues found" << endl;
    }
}

int main()
{
    boost::thread_group g;
    g.create_thread(check_thread);
    g.join_all();
    return 0;
}
