title: subtract time away from a php date time
body: <p>I have a report I built but the problem is the datetimes in the database for the 3 major events are the same as the system processes then so fast, there is no easy way about it as I aggregate data from 4 servers into one jquery datatable and sort by date time decending.</p>
  
  <p>So my question is how can I take a variable in PHP (string of mysql format date time), and reduce it by 1 second?</p>
