A convenience struct to easily measure time since an event last happened, based on <see cref="P:Sandbox.Time.Now" />.<br /><br /> Typical usage would see you assigning 0 to a variable of this type to reset the timer. Then the struct would return time since the last reset. i.e.: <code> TimeSince lastUsed = 0; if ( lastUsed > 10 ) { /*Do something*/ } </code>
