Add date and time stamp to continuously streaming data

Hi all,

I am new to the LabView Environment and I am trying to setup a program to perform the following:

1. Prompt users to select an experiment 

2. Display prompt messages to guide the users through an experiment

3. Collect Data from NI-DAQ in continuous mode.

I have completed task 1 and 2 but for task 3, I want to add time stamp adjacent to each data acquired. But I have not been able to do so. Please suggests what changes can I make to the attached VI to achieve my goals. 

PS: Any suggestions on making the VI better would be highly appreciated.

Thanks
