Detailed Description

template<typename TimeTraitsT>
class boost::attributes::basic_clock< TimeTraitsT >

A class of an attribute that makes an attribute value of the current date and time.

The attribute generates current time stamp as a value. The type of the attribute value is determined with time traits passed to the class template as a template parameter. The time traits provided by the library use boost::posix_time::ptime as the time type.

Time traits also determine the way time is acquired. There are two types of time traits provided by the library: utc_time_traits and local_time_traits. The first returns UTC time, the second returns local time.
