data to time stamp

Hi.

I have a problem, I have the time data in one excel file, one cell contains the value that correspond to the hours, another the minutes, another the seconds, I want to get this data in labview in this form 00:00:00:000. Is it possible to do? 

I tried to do with the tools in the timing menu, but I did not get it.

I attached some images from my excel file and my code.

Thanks.
