Public Methods

Method	Description
GetBootTime ( Time time ) : void	Retrieves the system boot time.
GetCurrentTime ( ) : Time
GetCurrentTime ( Time time ) : void	Retrieves the current system clock time.
GetCurrentTimestamp ( ) : ulong
GetHardwareTime ( Time time ) : bool	Retrieves the current hardware time. If this is not possible, this method returns false.
GetHardwareTimestamp ( ) : ulong	Retrieves the current hardware time as a timestamp. If this is not possible, this method returns 0.
GetNanostamp ( ) : ulong	Returns the amount of nanoseconds since the last ResetNanostamp() call. This value is limited in precision to the frequency of the system timer.
ResetNanostamp ( ) : void	Resets the nanostamp counter.
Setup ( ) : void	Initializes the system clock. First the hardware time is read and stored as the boot time and current time. The times are stored as 64-bit unsigned integers with 100-nanosecond ticks since the epoch (January 1, 0001, 00:00:00). A handler is added to the system timer event which updates the current time and handles periodic synchronization with the hardware time. The amount added to the current time per timer fire is relevant to the frequency reportedly used by the system timer.

Property Details

HardwareSyncTicks public_oe static_oe property

The interval of time (in 100-nanosecond ticks) between synchronizations from the hardware clock to the software clock. (default 600000000 ticks is 1 minute).
