int set_next_reset(int delay)
Instruct the gamedriver to reset this object not earlier than
in <delay> seconds. If a negative value is given as delay, the object
will never reset (useful for blueprints). If 0 is given, the
object's reset time is not changed.
Result is the former delay to the objects next reset (which can be
negative if the reset was overdue).
Note that the actual time the reset occurs depends on when
the object will be used after the given time delay.
set_next_reset(15*60); // Next reset in 15 Minutes or later
set_next_reset(0) --> just returns the time until the
