title: substract minutes from time using vb.net
body: <p>I need to substract some minutes from a spesific hour and show the output. For example, substract 10 minutes from 14:50 and show the output as 14:40.</p>
  
  <p>How can i do that? I have tried datediff function but It doesn't work for that I guess. I also tried date.substract but I couldn't solve the issue with that either. </p>
  
  <p>Thanks in advance. </p>
