pawn Code:

public OnPlayerCommandText(playerid, cmdtext[])
{
  if(strcmp("/command", cmdtext, true, 9) == 0)
  {
    if(GetPVarInt(playerid,"WAITBEFOREUSINGITAGAIN")>GetTickCount())return SendClientMessage(playerid,Colour,"ERROR : You must wait before using a command");
    SetPVarInt(playerid,"WAITBEFOREUSINGITAGAIN",GetTickCount()+5000); // 1000 = 1 secs
    // Put some codes here
  }
  return 1;
}

Same goes to dcmd and zcmd

EDIT : Oh shi... Better look at the time and date next time >.>
