Detailed Description

DtSynchronizedTimeManager manages NTP synchronized time DtSynchronizedTimeManager is used by the display engine to provide an NTP synchronized time value, allowing users of this time to be synchronized across applications.

Currently time scaling is not supported if using NTP- synced clocks.

Constructor & Destructor Documentation

virtual makVrv::DtSynchronizedTimeManager::~DtSynchronizedTimeManager ( )

inlinevirtual

DTOR.

makVrv::DtSynchronizedTimeManager::DtSynchronizedTimeManager ( DtDe &  de )

protected

Protected CTOR. This class may only be constructed using DtSynchronizedTimeManagerCreator.

makVrv::DtSynchronizedTimeManager::DtSynchronizedTimeManager ( )

private

Unimplemented default CTOR.

makVrv::DtSynchronizedTimeManager::DtSynchronizedTimeManager ( const DtSynchronizedTimeManager &  orig )

private

Unimplemented copy constructor.

Member Function Documentation

virtual double makVrv::DtSynchronizedTimeManager::syncedTime ( ) const

virtual

Returns synchronized time if the synchronized time flag has been set; otherwise reverts to standard DtDe::simulationTime()

virtual double makVrv::DtSynchronizedTimeManager::timeEpoch ( ) const

virtual

To get millisecond resolution when starting from a absolute clock its necessary to reckon time from a starting point much closer to current clock time than.

1. This returns the epoch that is calculated by calcTimeEpoch(), which is Midnight of the day the application is run at.

virtual void makVrv::DtSynchronizedTimeManager::setTimeScaleFactor ( double  scale )

virtual

Set / get a scale factor for time.

virtual double makVrv::DtSynchronizedTimeManager::timeScaleFactor ( ) const

virtual

virtual void makVrv::DtSynchronizedTimeManager::calcTimeEpoch ( )

protectedvirtual

Calculate the starting time from which the synchronized time is measured.

This uses midnight of the current day.

DtSynchronizedTimeManager& makVrv::DtSynchronizedTimeManager::operator= ( const DtSynchronizedTimeManager &  rhs )

private

Unimplemented assignment operator.
