Usage 
fractionalSec = bufferVar.fractionalseconds[N] 
The fractional second portion of the timestamp to 1 ns resolution 
The name of the reading buffer, which may be a default buffer (defbuffer1 or
defbuffer2
) or a user-defined buffer
The reading number N; can be any value from 1 to the number of readings in the 
buffer; use the bufferVar.n command to determine the number of readings in the
Details 
This read-only attribute is an array of the fractional portion of the timestamp, in seconds, when each 
reading occurred. Seconds are shown as fractions. 
Example 
 
testData = buffer.make(50) 
trigger.model.load("SimpleLoop", 6, 0, testData) 
trigger.model.initiate() 
waitcomplete() 
print(testData.fractionalseconds[1]) 
printbuffer(1, 6, testData.fractionalseconds) 
Create a reading buffer named testData and make six measurements.
Print the fractional portion of the timestamp for the first reading in the buffer. 
Example output: 
0.647118937 
Print the fractional portion of the timestamp for the first six readings in the buffer. 
Example output: 
0.647118937, 0.064543, 0.48196127, 0.89938724, 0.316800064, 0.734218263
