Time Stamps in Producer/Consumer Setup

Question

I am trying to acquire signal from a Gas Analyzer, Flow Meter, and 3 RTDs.  My hardware is a NI 9215 and NI 9217.  I need to write the data to a file with a time stamp at which the sample was read.  The program is written in a producer/consumer setup in which the data is being acquired in the prodcuer loop and sent to the consumer loop to be written.  I can get the samples written to the file okay. However, I have not figured out how to put the time stamp in the data file correctly. I thought the time stamp was created with the corressponding measurement at the Data Acquisition VI. However, whenever I open the data file, there are only 0s in the time column.  So, I've tried to use Format/Date String to add the time stamp. I can get it to work if I place it in the consumer loop. However, the time stamp is not accurate.  It puts the same time stamp up to six digits of precision for two consecutive samples. I've tried to figure out how to add it to the producer  loop, but I don't know how to add it and the measurements to the queue at the same time. Please tell me the best way to acquire signals with the exact time stamp and write them to a file using a producer/consumer design.
 Example:
Date             Time               RTD1     RTD2      RTD3     CO2      Flow
5/26/07      5:20:01.25       57         56         56.5      100       0.5
5/26/07      5:20:01.30       57         56         56.5      100       0.5
5/26/07      5:20:01.35       57         56         56.5      100       0.5

Answer 1

Okay, I've put it in a For Loop and it will connect now. However, whenever it runs the time stamp increments for a couple seconds and then it just repeats. How do I correct this?
