The Relative property of the RealTimeSince struct provides the time that has passed since the last reset, measured in seconds. This property is useful for tracking elapsed time in a straightforward manner, allowing developers to easily determine how much time has passed since a particular event occurred.

To use the Relative property, you typically initialize a RealTimeSince variable to zero when an event occurs. The Relative property will then automatically update to reflect the time elapsed since that initialization. This can be particularly useful for timing events or implementing cooldowns in a game.

Example usage:

RealTimeSince lastActionTime = 0;

// In an update loop or method
if (lastActionTime > 5.0f)
{
    // Perform an action if more than 5 seconds have passed since last reset
    lastActionTime = 0; // Reset the timer
}
