title: Oracle: How to select current date (Today) before midnight?
body: <p>Using Oracle, how do you select current date (i.e. SYSDATE) at 11:59:59?</p>
  
  <p>Take into account that the definition of midnight <a href="https://english.stackexchange.com/questions/6459/how-should-midnight-on-be-interpreted">might be a little ambiguous</a> (Midnight Thursday means Straddling Thursday and Friday or Straddling Wednesday and Thursday?).</p>
