Yes, you can, and it seems to work well (at least in 1.35). Look at this example: http://www.boost.org/doc/libs/1_35_0/doc/html/boost_asio/tutorial/tuttimer4....

I am seeing irregular behaviour around resetting already expired timers - sometimes they fail to function. I am resetting the timer by using expires_from_now method. (Boost 1.34.1 with asio 0.3.9)Thanks,Sharad _________________________________________________________________ Connect to the next generation of MSN Messenger http://imagine-msn.com/messenger/launch80/default.aspx?locale=en-us&source=wlmailtagline
