What is this date and time format?

Question

I was wondering if anyone knows this time-format:

• the value 635872032000000000 represents the 01.Jan 2016.
• the value 636502752000000000 represents the 31.Dec 2017.

I googled the value and found, that sharepoint is taking this as a parameter too.

Does someone know the format, how to use it or where it's from?

Answer 1

These dates are represented in ticks:

ticks Type: System.Int64

A date and time expressed in the number of 100-nanosecond intervals that have elapsed since January 1, 0001 at 00:00:00.000 in the Gregorian calendar.

e.g. C# code

  long value = 635872032000000000L;

  DateTime result = new DateTime(value);

  Console.Write(result);
