If you really want to round the time to the nearest second, you can use:

DateTime.MinValue
        .AddSeconds(Math.Round((DateTime.Now - DateTime.MinValue).TotalSeconds));

However unless that extra half a second really makes a difference, you can just remove the millisecond portion:

DateTime.Now.AddTicks( -1 * (DateTime.Now.Ticks % TimeSpan.TicksPerSecond));
