title: Would changing local OS time affect the database?
body: <p>Currently our stand-alone 11g R2 Oracle database has the wrong time as the local OS server (Linux redhat) also has the wrong time (off by several minutes). </p>
  
  <p>Can I just ask a sysadmin to change the OS time by several minutes; does that affect the database? Does the database need to be restarted after the local OS time changed has been changed? Does database need to be down while doing this?</p>
