The sample project ‘DigitalWatch’ has the following code:

function updateDate(prevDay) {
        var datetime = tizen.time.getCurrentDateTime(),
            nextInterval,
            strDay = document.getElementById("str-day"),
            strFullDate,
            getDay = datetime.getDay(),
            getDate = datetime.getDate(),
            getMonth = datetime.getMonth();

        // Check the update condition.
        // if prevDate is '0', it will always update the date.
        if (prevDay !== null) {
            if (prevDay === getDay) {
                /**
                 * If the date was not changed (meaning that something went wrong),
                 * call updateDate again after a second.
                 */
                nextInterval = 1000;
            } else {
                /**
                 * If the day was changed,
                 * call updateDate at the beginning of the next day.
                 */
                // Calculate how much time is left until the next day.
                nextInterval =
                    (23 - datetime.getHours()) * 60 * 60 * 1000 +
                    (59 - datetime.getMinutes()) * 60 * 1000 +
                    (59 - datetime.getSeconds()) * 1000 +
                    (1000 - datetime.getMilliseconds()) +
                    1;
            }
        }

        if (getDate < 10) {
            getDate = "0" + getDate;
        }

        strFullDate = arrDay[getDay] + " " + getDate + " " + arrMonth[getMonth];
        strDay.innerHTML = strFullDate;

        // If an updateDate timer already exists, clear the previous timer.
        if (timerUpdateDate) {
            clearTimeout(timerUpdateDate);
        }

        // Set next timeout for date update.
        timerUpdateDate = setTimeout(function() {
            updateDate(getDay);
        }, nextInterval);
    }

1. At first the method ‘updateDate(prevDay)’ is called with 0 parameter;

2. In the end this method sets a timeout with the particular time interval to call itself again but with the other parameters (0 ‘Sun’, 1 ‘Mon’, 2 ‘…’, 3, 4, 5, 6);

If the application is started on Monday (1 is a parameter for Monday) the method sets the correct time interval (23:59:59:1000 minus actual time) however the wrong time interval (1 second) is set if the application is started on Sunday (0 is a parameter for Sunday), so this updateDate(prevDay) method is called every second the whole day until the next day.

So I’ve changed the argument to -1 and the application works fine now.

I don’t think it is normal. How do you think?
