DateTimeNowButton has a deprecated constructor

Hi, wen I activated WP_DEBUG I get the following message of a deprecated constructor that will soon not be supported anymore. Is there a plan to update the plugin or can someone recommend a new one?

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; DateTimeNowButtonPlugin has a deprecated constructor in /wp-content/plugins/datetime-now-button/datetime-now-button.php on line 14
