/// seconds, milliseconds or microseconds. It also works the
/// other way round: you can read a time value as either
/// a number of seconds, milliseconds or microseconds.
///
/// By using such a flexible interface, the API doesn't
/// impose any fixed type or resolution for time values,
/// and let the user choose its own favorite representation.
///
/// Time values support the usual mathematical operations:
/// you can add or subtract two times, multiply or divide
/// a time by a number, compare two times, etc.
///
/// Since they represent a time span and not an absolute time
/// value, times can also be negative.
///
/// Usage example:
/// \code
/// sf::Time t1 = sf::Seconds(0.1f);
/// Int32 milli = t1.AsMilliseconds(); // 100
///
/// sf::Time t2 = sf::Milliseconds(30);
/// Int64 micro = t2.AsMicroseconds(); // 30000
///
/// sf::Time t3 = sf::Microseconds(-800000);
/// float sec = t3.AsSeconds(); // -0.8
/// \endcode
///
/// \code
/// void Update(sf::Time elapsed)
