makVrv::DtDeTimeManager Class Reference

The time manager is responsible for maintaining the currenting date and time of the scene. It is also responsible for updating the time when the terrain changes, and querying the time of the observer.

Member Function Documentation

virtual void makVrv::DtDeTimeManager::setReferenceDateAndTime ( int  year, Month  month, int  dayOfMonth, int  hours, int  minutes, double  seconds  )

virtual

Set the reference date and time, used for calculating the current date and time.

Set the current date.

virtual void makVrv::DtDeTimeManager::getReferenceDateAndTime ( int &  year, Month &  month, int &  dayOfMonth, int &  hours, int &  minutes, double &  seconds  ) const

virtual

Get the last set date.

virtual void makVrv::DtDeTimeManager::syncReferenceDateAndTime ( )

virtual

Set the reference date and time to the current date and time.

virtual void makVrv::DtDeTimeManager::setUseGlobalTimeZone ( bool  )

virtual

When displaying the sun/moon position, use the observer (default, suppling false to this method) or use the current GMT time (supplying true to this method)

virtual bool makVrv::DtDeTimeManager::useGlobalTimeZone ( ) const

virtual

Returns whether or not to use GMT Time for observer.

virtual void makVrv::DtDeTimeManager::calculateCurrentDateAndTime ( int &  year, Month &  month, int &  dayOfMonth, int &  hour, int &  minutes, double &  seconds  ) const

virtual

Calculate the current date and time based upon the simulation time passes since the reference was set.

static bool makVrv::DtDeTimeManager::isYearALeapYear ( int  year )

static

Check to see if this is a leap year.

static int makVrv::DtDeTimeManager::daysInTheMonthOf ( int  year, Month  month  )

static

Get the number of days in a month. The year is necessary for getting Leap days.

static Month makVrv::DtDeTimeManager::nextMonth ( Month  month )

static

Get the next month.

virtual double makVrv::DtDeTimeManager::timeScale ( ) const

virtual

Get the time scale.

virtual void makVrv::DtDeTimeManager::setTimeScale ( double  timeScale )

virtual

Set the time scale, this will also set the time base upon the current time scale.

Reimplemented in makVrf::DtVrfDeTimeManager.

virtual void makVrv::DtDeTimeManager::getRecord ( makArchives::DtDateTimeRecord &  record ) const

virtual

Fill out a record with the current date/time and timescale.

double makVrv::DtDeTimeManager::timeSinceSet ( ) const
