void CTimeManager::SetLocalDateTime (  SDateTime  dt  ) 
 

Set the simulation date and time in Local Time. Local time zone is initialized from the user's computer, unless overridden by a call to the SetTimeZoneDelta method.

Parameters:
dt Date/Time in SDateTime struct

void CTimeManager::SetTimeZoneDelta (  bool  subtract,
SDateTimeDelta  delta
) 
 

Set the local time zone offset relative to UTC. This offset will be used for all subsequent conversions from UTC to local time. Note that the simulation time (which is stored as UTC) is not affected when the local time zone offset is updated

Parameters:
subtract true if time zone delta is subtracted from UTC, false if it is added to UTC
delta Time zone delta in SDateTimeDelta struct

Definition at line 144 of file TimeManager.cpp.

References tzDelta, and tzSubtract.

void CTimeManager::SetTimeZoneOffset (  float  offset  ) 
 

Set the local time zone offset relative to UTC. This offset will be used for all subsequent conversions from UTC to local time. Note that the simulation time (which is stored as UTC) is not affected when the local time zone offset is updated

Parameters:
offset Offset of local timezone from UTC, in hours
