Boost C++ Libraries: Ticket #6835: Timer and Sleep issues with system clock

Fri, 04 May 2012 14:58:55 GMT

Hi,

Anybody witnessed the same issue or tried to replicate it?

This can cause serious issues in some situations where the clock is set when the code is running.

Thanks

The asio::deadline_timer typedef uses the UTC clock, as documented here.

If you don't want to be sensitive to UTC clock changes then use the new asio::steady_timer typedef, or write your own custom time traits to use an alternative clock as shown in this example.

Hi chris,

Thanks for the steady_timer pointer. Do you have a similar suggestion for other timing related calls? (this_thread::sleep)

Regards, Luc

You could use steady_timer's synchronous wait() function.

Was that also changed in condition_variable (timed_wait)?

Thanks, Luc

Not my area, sorry.
