title: In Google sheets, how does one either return a blank cell or perform a function based on another cells lack of content?
body: <p>This is what I have thus far:</p>
  
  <pre><code>=if(ISBLANK(A:A), (A:A+TIME(2, 0, 0)), "")
  </code></pre>
  
  <p>I'd like the script to add 2 hours to A:A or just remain blank if there is no data inside A:A</p>
  
  <p>Any ideas would be greatly appreciated. Thank you :)</p>
