/// sf::Time encapsulates a time value in a flexible way.
|

/// It allows to define a time value either as a number of
|
||||
/// 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

///
