.NET, event every minute (on the minute). Is a timer the best option?

by

Building on the answer from aquinas which can drift and which doesn’t tick exactly on the minute just within one second of the minute:

static System.Timers.Timer t;

static void Main(string[] args)
{
    t = new System.Timers.Timer();
    t.AutoReset = false;
    t.Elapsed += new System.Timers.ElapsedEventHandler(t_Elapsed);
    t.Interval = GetInterval();
    t.Start();
    Console.ReadLine();
}

static double GetInterval()
{
    DateTime now = DateTime.Now;
    return ((60 - now.Second) * 1000 - now.Millisecond);
}

static void t_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    Console.WriteLine(DateTime.Now.ToString("o"));
    t.Interval = GetInterval();
    t.Start();
}

On my box this code ticks consistently within .02s of each minute:
