I need to write a method to get day of week (pacific time) for current time. Is the following code correct?

static Calendar s_calendar = Calendar.getInstance(Locale.US);
static {
    s_calendar.setTimeZone(TimeZone.getTimeZone("America/Los_Angeles"));
}

public static int getDayOfWeek() {
    s_calendar.setTimeInMillis(System.currentTimeMillis());
    return s_calendar.get(Calendar.DAY_OF_WEEK);
}

Thanks.
