Answer 1

If you want to start a timer at exactly 00:01:00am do some processing time and then restart the timer you just need to calculate the difference between Now and the next 00:01:00am time slot such as.

static Timer timer;
static void Main(string[] args)
{
    setup_Timer();
}

static void setup_Timer()
{
    DateTime nowTime = DateTime.Now;
    DateTime oneAmTime = new DateTime(nowTime.Year, nowTime.Month, nowTime.Day, 0, 1, 0, 0);
    if (nowTime > oneAmTime)
        oneAmTime = oneAmTime.AddDays(1);

    double tickTime = (oneAmTime - nowTime).TotalMilliseconds;
    timer = new Timer(tickTime);
    timer.Elapsed += timer_Elapsed;
    timer.Start();
}

static void timer_Elapsed(object sender, ElapsedEventArgs e)
{
    timer.Stop();
    //process code..
    setup_Timer();
}
