 ## Remarks  
  A single tick represents one hundred nanoseconds or one ten-millionth of a second. There are 10,000 ticks in a millisecond, or 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 (0:00:00 UTC on January 1, 0001, in the Gregorian calendar), which represents <xref:System.DateTime.MinValue?displayProperty=nameWithType>.

+If the DateTime object has its `Kind` property set to `Local`, its ticks represent the time elapsed time since 12:00:00 midnight, January 1, 0001 in the local time as specified by the current time zone setting.
+If the `DateTime` object has its `Kind` property set to `Utc`, its ticks represent the time elapsed time since 12:00:00 midnight, January 1, 0001 in the Coordinated Universal Time.
+If the `DateTime` object has its `Kind` property set to `Unspecified`, its ticks represent the time elapsed time since 12:00:00 midnight, January 1, 0001 in the unknown time zone.

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