PHP код:

new gifttimer[MAX_PLAYERS]; //on top of script 


in /gift command.

PHP код:

CMD:gift(playerid,params)
{
//code
if(gifttimer[playerid] > gettime()) return SendClientMessage(playerid,COLOR_YELLOW,"You need to wait for 1 day to use this command again");
gifttimer[playerid] = gettime()+86400;
return 1;
} 


This will reset the /gift after 1 full day.
