DateTime Comparison Precision

Question

I\'m doing DateTime comparison but I don\'t want to do comparison at second, millisecond and ticks level. What\'s the most elegant way?

If I simply compare the DateT

Answer 1

Another way is to convert first by processing on ticks level with a simple (non-rounding) calculation:

var now = DateTime.UtcNow;
// 636340541021531973, 2017-06-26T06:08:22.1531973Z

var millisecondsPrecision = new DateTime(now.Ticks / 10000 * 10000, now.Kind);
// 636340541021530000, 2017-06-26T06:08:22.1530000Z

var secondsPrecision = new DateTime(now.Ticks / 10000000 * 10000000, now.Kind);
// 636340541020000000, 2017-06-26T06:08:22.0000000Z

var minutePrecision = new DateTime(now.Ticks / (10000000*60) * (10000000*60), now.Kind);
// 636340541000000000, 2017-06-26T06:08:00.0000000Z
