Write the interval to a std::ostream.

Detailed Description

Time interval.

Constructor & Destructor Documentation

shevek::relative_time::relative_time (timetypeseconds, unsignednanoseconds)

Fast constructor. This directly fills the members and is therefore slightly faster than the other constructors. However, the others aren't really slow either.

Member Function Documentation

bool shevek::relative_time::operator!= (relative_timethat) const

Compare two intervals. Note that this is rarely a useful operation, because minor errors may be introduced by computations.

bool shevek::relative_time::operator== (relative_timethat) const
