Why do you need an timer that checks if an hour passed?
Just create a timer who gets called each hour

pawn Код:

SetTimer("EachHour", 1000 * 60 * 60, true);

To sycn it with the clock you just calculate the remaining seconds and call than the timer

pawn Код:

// OnGameModeInit
    HourTimer();
// global
forward HourTimer();
public HourTimer() {
    // code

    new
        hour,
        minute,
        second
    ;
    gettime(hour, minute, second);
    SetTimer("HourTimer", (3599 - minute * 60 - seconds) * 1000, false);
}
