Properties

Name	Value	Type	Description	Subproperties
control_simulation_clocks	false	tBool	If enabled, then the current simulation clock used as stream clock, will be started and stopped upon runlevel changes.	Value Range: minimum = maximum = Filename Extension Filter:
default_sync2ref_method	adtf_default	cString	Synchronization algorithm used mapping non-system timestamps (e.g. from remote devices) to ADTF Streamtime for Sample timestamps.	Extendable Value List: adtf_default = adtf_defaultValue Range: minimum = maximum = Filename Extension Filter:
local_time_strings	true	tBool	If enabled timestamp strings will be interpreted/generated with respect to the local timezone.	Value Range: minimum = maximum = Filename Extension Filter:
simulation_clock/end		cString	The stop time of the simulation clock as a UTC timestamp (i.e. '1970-01-01T00:00:00'). This is only used when 'control_simulation_clocks' is activated.	Value Range: minimum = maximum = Filename Extension Filter:
simulation_clock/speed	1.000000	tFloat64	The speed at which the simulation clock advances relative to the wall clock. A value of zero indicates maximum speed. This is only used when 'control_simulation_clocks' is activated.	Value Range: minimum = maximum = Filename Extension Filter:
simulation_clock/start	1970-01-01T00:00:00	cString	The start time of the simulation clock as a UTC timestamp (i.e. '1970-01-01T00:00:00'). When empty, the clock is not reset. This is only used when 'control_simulation_clocks' is activated.	Value Range: minimum = maximum = Filename Extension Filter:
simulation_clock/system_clock	false	tBool	Whether or not the simulation clock should advertise itself as system clock or not. This is only used when 'control_simulation_clocks' is activated.	Value Range: minimum = maximum = Filename Extension Filter:
simulation_clock/try_realtime_simulation	true	tBool	If this property is true, the hardware clock of the host will be used to determine when the time should advance. Otherwise the clock will simply sleep for the time difference between the time barriers. This is usefull when using a debugger. This is only used when 'control_simulation_clocks' is activated.	Value Range: minimum = maximum = Filename Extension Filter:
stream_clock	system	cString	Registered clock which will be used to provide the ADTF Streamtime.	Extendable Value List: adtf_stream = adtf_stream system = system discrete_simulation = discrete_simulation continuous_simulation = continuous_simulationValue Range: minimum = maximum = Filename Extension Filter:
time_guard_compatibility_mode	0	tUInt32	Compatibility mode for stream clocks that do not support time guards	Value List: continuous clock = 0 discrete clock = 1Value Range: minimum = maximum = Filename Extension Filter:
time_stamp_epoch	1970-01-01T00:00:00	cString	The epoch used for converting timestamps.	Value Range: minimum = maximum = Filename Extension Filter:
