I have the following time : 2010-01-25 03:13:34.384 - GMT Time Zone 2010-01-25 11:13:34.384 - My Local
I wish to convert to timestamp in ms. However, since I only obtain local time string from caller "2010-01-25 11:13:34.384"
If I do it this way :
// ts is "2010-01-25 11:13:34.384" (My Local) boost::posix_time::ptime t(boost::posix_time::time_from_string(ts)); boost::posix_time::ptime end(boost::gregorian::date(1970,1,1)); boost::posix_time::time_duration dur = t - end; // epoch is 1264418014384 // 2010-01-25 11:13:34.384 (GMT) -- But I want 2010-01-25 03:13:34.384 // 2010-01-25 19:13:34.384 (My Local) -- But I want 2010-01-25 11:13:34.384 long long epoch = dur.total_milliseconds();
Is there any way to tell boost::posix_time, that the ts string which it receives, is belong to My Local timezone?
I thought posix_time is always supposed to be UTC, you are not feeding it UTC? There is probably something to convert it though, not sure on what. Perhaps there was something other then posix_time to feed it into first?
