Hi Boost Users, I am attempting to use the boost library date_time to create a platform independent function to get the system time in milliseconds. Basically, I need a millisecond precision timing mechanism. I read over the docs and looked at the examples from this library and came up with something that I thought would work, but it doesn't. :( ptime time_t_epoch(date(1970,1,1)); time_zone_ptr zone(new posix_time_zone("MST-07")); local_date_time dt_epoch(time_t_epoch, zone); time_zone_ptr zone2(new posix_time_zone("MST-07")); local_date_time ldt = local_microsec_clock::local_time(zone2); time_duration diff = ldt.utc_time() - dt_epoch.utc_time(); long milli = diff.total_milliseconds(); cout << milli << endl; What I get is a negative number. The function I want should have the exact same behavior as java.lang.System.currentTimeMillis() which returns "the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC." Is there a way to achieve this with boost? Is so, can someone please give me some hints as to how I can do this? many thanks for your help! -B
