Just as a follow up to this, let me describe what I'm trying to do. I would like the current time in UTC with microsecond resolution. Well, the microsec_clock class only provides a local_time() method (unlike the second_clock class which also provides universal_time()). So, I need to convert the result of local_time() into UTC but I can't since the only class which knows the local timezone is c_local_adjustor and it does not provide local_to_utc() (only utc_to_local()). If there is a better way to get the current time in UTC with microsecond resolution, I'd be happy to use it instead. Thanks, Sean -----Original Message----- I'm even more confused after looking at the URL and test file you suggested. All of the examples in those documents require you to explicitly construct and provide a time zone using a name or an offset from UTC. I don't want to have to hardcode a timezone in my program -- I just want to use whatever time zone that the user has configured on their computer. The c_local_adjustor did this for me in 1.32 (although as noted in my original email, it only solves half of the problem). Perhaps I missed something in the URL you sent, but I didn't see anything in there which simply uses the timezone in use on the local machine.

I am using the boost date_time library and noticed that there is a from_ftime() function to convert a FILETIME into a ptime, but I could not find the reverse operation to_ftime(). Am I missing it somewhere?
No. FILETIME, as you're certainly aware, is a Windows only way to measure time. This function is there primarily to support conversion from legacy applications. If there's really some need it's not hard to support.
Likewise, I am using the c_local_adjustor::utc_to_local() function and
cannot find the corresponding local_to_utc() function in c_local_adjustor.
In 1.33 there is vastly enhanced support for local time conversion via the timezone class and it's friends posix_timezone and tz_database. See <http://engineering.meta-comm.com/resources/cs-win32_metacomm/doc/html/d ate_time/local_time.html#date_time.local_time.time_zone_base> for more on this. If you still want to use the compile time approach supported in 1.32, have a look at libs/date_time/test/posix_time/testlocal_adjustor.cpp. There's code in there that show how to convert back and forth.
