Can you start googling instead of just asking everything? I know
nothing about the topic but a quick google brings up asio's
deadline_timer frequently, have a look at that. e.g.
http://stackoverflow.com/questions/4267546/c-boost-asio-simple-periodic-timer

You could have found this in much less time than it took to fire an
email to the list...

In fact, I did google a bit before "firing" an email! The thing is that I had inquired about it already sometime ago on this mailing list and it turned out that ASIO Deadline Timer does not work well when the host time changes. Unfortunately, host time does change quite often where my app is supposed to run. So, I was wondering if another better solution has emerged in Boost libraries. I also looked at Chrono but it was not immediately apparent to me as to whether it does support periodic interval timer or not.
