[Boost-users] Boost ASIO steady_timer and date change

Hello,

I'm using a steady_timer to perform an asynchronous wait in the following manner:

boost::asio::io_service io_service;
boost::asio::steady_timer my_timer(io_service);

void onTimeout(const boost::system::error_code& e)
{
    // Print something
}

...
my_timer.expires_from_now(std::chrono::seconds(600));
my_timer.async_wait(onTimeout);
io_service.run();

If system 'date' does not change, everything is ok. But if I change 'date' by hand while the timer is running, it expires before 600 seconds (more or less after 5 minutes) and 'onTimeout' is called. With synchronous wait, all is ok.
According to documentation, steady_timer should not be affected by time change.
Which may be the problem?

Thanks,
Sabino
