public static function get TickCount () : int
Property Value
Type:
System..::.Int32A 32-bit signed integer containing the amount of time in milliseconds that has passed since the last time the computer was started.
The value of this property is derived from the system timer and is stored as a 32-bit signed integer. Consequently, if the system runs continuously, TickCount will increment from zero to Int32..::.MaxValue for approximately 24.9 days, then jump to Int32..::.MinValue, which is a negative number, then increment back to zero during the next 24.9 days.
TickCount is different from the Ticks property, which is the number of 100-nanosecond intervals that have elapsed since 1/1/0001, 12:00am.
Use the DateTime..::.Now property to obtain the current local date and time on this computer.
The following code example demonstrates how to retrieve the positive range of values returned by the TickCount property. The TickCount property cycles between Int32..::.MinValue, which is a negative number, and Int32..::.MaxValue once every 49.8 days. This code sample removes the sign bit to yield a nonnegative number that cycles between zero and MaxValue once every 24.9 days.

' TickCount cycles between Int32.MinValue, which is a negative
' number, and Int32.MaxValue once every 49.8 days. This sample
