This post is related to my discovery of differences in behavior between 
posix_time::from_ftime and C# DateTime.FromFileTime methods (earlier post)

Now I am trying to learn the proper usage of posix_time and time_zones. After 
reading the documentation I am still confused regarding usage of the timezone 
together with usage of classes/functions in posix_time namespace

 Is it possible to do smth.like this: First declare the time zone, like EST, 
CT ets and then all subsequent calls to posix_time namespace functions or 
classes will take this timezone as a base?

I will really appreciate a simple example of specifying EST timezone for 
posix_time.
