Hello, I want to provide some integration between boost::posix_time::ptime and boost::locale::date_time - make transparent conversion between two. I have following point I either miss in ptime design or it has design flaws: 1. POSIX Time (see http://en.wikipedia.org/wiki/Unix_time) is always considered Time in seconds from 1970-JAN-1 00:00:00 UTC not including leap seconds. However ptime can be constructed from "local_time" which is totally contradicts a well known definition of POSIX time. 2. I can't find any way to convert it to "number" POSIX time. I can convert it to time_t and from time_t but if I need a better accuracy -milli-seconds, nano-seconds etc. it seems to be impossible according to docs. How can I convert it to more accurate representation? Is there any way to get a notice about how ptime was created, with universal time scale or local time scale, also I there a way to get UTC POSIX time from ptime even if it was created from local time.
