Function set_wander_time():
Defined in module m_wander (file: /std/modules/m_wander.c)

Sets the time between an NPC's movements.  

If the argument is an int it sets the time in seconds.

If the argument is a function pointer, the function 
needs to evaluate to an int.  The fpointer is evaluated
during runtime.

Prototype:
void set_wander_time(mixed time);
