<div class="markdown_content"><p><em>Originally created by:</em> 99bobster99</p> <p>I think I figured it out. Please let me know if there is an easier way to do this. I converted my DT variable to a DWORD, then subtracted 18000 from it. This seems to work for me, but kind of ugly.</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> 99bobster99</p> <p>Hello,</p> <p>I am a Codesys newbie. How do you subtract 5 hours from a DT variable? I searched Google, but could not find anything relating to this procedure.</p></div>
