What are `ticks`?

A single tick represents one hundred nanoseconds or one ten-millionth of a second. There are 10,000 ticks in a millisecond and 10 million ticks in a second.

The value of this property represents the number of 100-nanosecond intervals that have elapsed since 12:00:00 midnight, January 1, 0001 in the Gregorian calendar, which represents MinValue. It does not include the number of ticks that are attributable to leap seconds.

In general, the ticks represent the time according to the time zone specified by the Kind property.
