title: Excel: Recalculating every x seconds
body: <p>One of my spreadsheets deals with various calculations involving, among other things, the current date and time and it would be nice to have it automatically refresh itself once in a while instead of manually having to either press F9 or altering one of the cells.</p>
  
  <p>Is there some way in Excel to set a spreadsheet to automatically recalculate itself every x seconds?</p>
  
  <p>I haven't been able to find a setting in Excel itself, perhaps indicating that no such feature exists. If not, can this be achieved with VBA? (The latter may or may not sound like a silly question, but I have no prior experience with writing Excel macros and as such have no idea what its capabilities are in terms of manipulating spreadsheets.)</p>
