TShock JIST script made to work in combination with STime to set real time.

real_time.js

function setSTime(t) {
        tshock_exec(tshock_server(), "/stime " + t);
}

function addZero(i) {
    if (i < 10) {
        i = "0" + i;
    }
    return i;
}

function getRealtime() {
        var d = new Date();
        var h = addZero(d.getHours());
        var m = addZero(d.getMinutes());
        var t = h + ":" + m;
        return t;
}

jist_task_queue(0, 0, 1, function() {
                var xt = getRealtime();
                setSTime(xt);
        }
);
