const std::shared_ptr< ElapsedTime > m_pTimeBase
#define CANVASTOOLS_DLLPUBLIC
bool m_bInHoldMode
True, when in hold mode.
double m_fLastQueriedTime
To validate adjustTimer() calls with bLimitToLastQueriedTime=true.
bool m_bInPauseMode
True, when in pause mode.
double m_fStartTime
Start time, from which the difference to the time base is returned.
double m_fFrozenTime
Instant, when last pause or hold started, relative to m_fStartTime.
