## Detailed Description

Represents a time value.

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:

* 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
*
* void update(sf::Time elapsed)
* {
* position += speed * elapsed.asSeconds();
* }
*
* update(sf::milliseconds(100));
*
