How to change the data time stamp from hh:mm:ss:ms to hh:mm:ss?

Hello,

I am new to labview. I have made a vi to record data after every 00:00:10 sec. However, my vi is recording data after every 00:00:10.9 sec. My vi is using the time from my desktop. Is there any way that I can make my vi to take reading after every 00:00:10 sec in place of after every 00:00:10.9 sec? I have attached my vi with this post. Kindly help me.

best wishes
