Based on truncating a DateTime to the second in C# while preserving the “Kind” (Local, UTC, Undefined):
dateTime = dateTime.AddTicks( - (dateTime.Ticks % TimeSpan.TicksPerSecond));
Thread.Sleep until the next 10 minute mark (e.g. Run every 00, 10, 20, 30, 40, 50 minutes):
Thread.Sleep(
TimeSpan.FromTicks(
(TimeSpan.TicksPerMinute * 10) -
(DateTime.Now.Ticks % (TimeSpan.TicksPerMinute * 10))
)
);Credit: http://stackoverflow.com/a/1005222/152852
In the real world, the above code appears to be waking up a fraction of a second too early. So perhaps adding an additional tick might be the way to go:
Thread.Sleep(
TimeSpan.FromTicks(
1 + (TimeSpan.TicksPerMinute * 10) -
(DateTime.Now.Ticks % (TimeSpan.TicksPerMinute * 10))
)
);
