laravel - how to modify original table attribute value for all tables
<p>Our company's DBA wants we set default value of <code>timestamp</code> table column to <code>1970-01-01 00:00:00</code>, but we have already written many programs that using <code>0000-00-00 00:00:00</code> to check <code>if</code> sentence.</p>

<p>We have used <strong>Laravel 5</strong> and <strong>MySQL 5.6</strong></p>

<p>If there are any solution that we can change all original column value which belong to <code>timestamp</code> type to <code>0000-00-00 00:00:00</code> when the time is <code>1970-01-01 00:00:00</code>?</p>

<p>Thank you very much.</p>
