title: Laravel - custom timestamp column names
body: <p>I am migrating a site from codeigniter to Laravel.</p>
  
  <p>For a legacy table <code>reports</code>, some existing columns <code>created_at</code> and <code>updated_at</code> are named <code>date_created</code> and <code>date_modified</code> respectively.</p>
  
  <p>I wish to tell my eloquent <code>Report</code> model about these custom timestamp column names.</p>
  
  <p>The documentation only provide reference to turning timestamps off or providing custom timestamp formats.</p>
