Hi, How can I convert a boost ptime to UTC given the current machine settings, without hard coding anything? I found the c_local_time_adjustor but it only has a utc_to_local() method. I tried reading through some of the local_time documentation but got lost with all the time zones. I realize they are important but for this application the software much always convert a ptime (that will be in the current machines local time) into UTC. I am running on Linux fwiw. Thanks for any help Wayne _________________________________________________________________ Your E-mail and More On-the-Go. Get Windows Live Hotmail Free. https://signup.live.com/signup.aspx?id=60969
