title: What timezone does Excel in Office 365/Sharepoint use for TODAY/NOW functions?
body: <p>When working on a Excel document in Sharepoint when I use the TODAY function I get odd results. It looks like the date is from the day before. I wonder what timezone does it use? Is that a setting or is it based on the browser I use?</p>
  <p>(Context: I'm using Sharepoint on a Kubuntu 20.04 desktop)</p>
