[Opensim-users] detection llGetSunDirection() day or night script 0.9.2 yengine error when shutdown region

[Luisillo Contepomi]

I am using this script for lamps years ago:
------------------------------
default {

   state_entry() {

      llSetTimerEvent(60);

   }

   timer() {

      vector sun = llGetSunDirection();

         if(sun.z > 0) {
       // llOwnerSay ("Es de dia");
        llSetLinkPrimitiveParams(LINK_THIS,[PRIM_FULLBRIGHT,2, FALSE]);

         }

         else {

        // llOwnerSay ("Es de noche");
        llSetLinkPrimitiveParams(LINK_THIS,[PRIM_FULLBRIGHT,2, TRUE]);

         }
   }
}
//////////end script
------------------------------


I have this Info notice in log when region go to shutdown:

I am doing some bad with  llGetSunDirection() or may be a bug?
Kind regards,
