Well, you are using the Dreaded DAQ Assistant (DDA, for short), meant for people who don't know (and don't want to learn) LabVIEW. TimeStamps are a special type in LabVIEW, and represent the number of seconds (to a very high precision) since 1 Jan 1904. Your DAQ Assistants are acquiring 10 points at 1 Hz. If you repeatedly generate 10 points and plot them, letting the X values repeat from 0 to 9 (or 1 to 10), and represent these numbers (0 to 10) as LabVIEW TimeStamps, they will evaluate to 1 Jan 1904, 00:00:00.0 to 00:00:01.0.
I recommend learning enough LabVIEW (a few weeks should do it) to be able to not use the DDA and use real DAQmx functions.
