text: Title: 'Last run X minutes ago' compares UTC to naive timestamp
  Body: This means they're incorrect unless your local timezone is equal to UTC.  
  
  In general, any newly generated report will have a 'last run' time of
  
  babel.dates.format_timedelta(datetime.datetime.utcnow() - datetime.datetime.now())
  
  and will just show your difference from UTC.
