- (NSTimeInterval) accumulatedTimestamp
readwritenonatomicassigninherited

Time values from the sensors are implemented as an offset in seconds between the time when the sensor is turned on and the time when a data sample is taken. This value is typically a 16-bit unsigned integer in units of 1/1024 second. The rollover is then 64 seconds.

A base real-time value is stored when the first sample from the sensor is received. The timestamp of each subsequent sample is the base time value offset by the time value offset from the sensor. If the time between samples is greater than the rollover time, the base time value is set to the time the first sample after the delay is received.

Note
The accumulator is initialized when the sensor is first connected, and reset via the resetAllSensorData (WFHardwareConnector) method.
