Hi,
In my application, I am collecting some data using the host machine and collecting some other data using my PXI machine. The thing that I want to make sure is that the timestamping on both the host and the real time machine are syncronized.To this end, I am trying to implement the example given at the following link
http://digital.ni.com/public.nsf/allkb/DC20E31E0067D76486257544005A1376
However, this example does not seem to be working in LabVIEW 2011. Is there anyone out there who can tell me why this is the case, or is there any other way of doing this.
Kind Regards,

As you told you have PXI system with Host. I hope you are acquiring the waveform data using PXI-DAQmx and by using some data transfer technique you are transfering this data to HOST. If you observer in DAQmx VI you have T0, here T0 indicate PXI time of acquisition. This time stamp you can use to configure the time of HOST. or same way you can transfer HOST time to PXI and initial step set the time and date of Host in PXI using RT date and time set function in Real time pallate.
Here for time synchronization no such direct method avaiable, one way that you have to buy new hardware from NI for time synchronization or you can program a logic to synchronize your Time between PXI and Host.

When you say it does not seem to be working what do you mean?
Did you simply run the project after you downloaded it from article?
