title: How to get a local date-time from a time_t with boost::date_time?
body: <p>I'm using boost::date_time and I got a time_t, that have been generated by a library using the time() function from the C standard library.</p>
  
  <p>I'm looking for a way get a local time from that time_t. I'm reading the documentation and can't find any way to do this without providing a time zone, that I don't know about because it's dependant on the machine's locale, and I can't find any way to get one from it.</p>
  
  <p>What am I missing?</p>
