Hi,

I'm using boost 1.47 on Visual Studio 2008 and cannot seem to get the time since epoch from the Chrono library.

At first I noticed that boost::chrono::system_time::now() does not have to be represented in time since epoch format so I don't believe that's an issue. However, I tried calling boost::chrono::system_time::now().time_since_epoch() and I get the same return result as if I was only referencing now(). That is, it is not time since epoch.

Calling the static method to_time_t() DOES return proper time since epoch but it is in seconds (as time_t generally is) and is not what I'm looking for.

Hi, the single difference between now() and now()::time_since_epoch() is that the first is a time_point, while the second is a duration. Could you post the code and your results, so we can see what is going wrong? Best, Vicente
