Roundcube 1.2 could not work with the following error

[Paul-LKW]

I just installed RC 1.2 with PHP-5.6.27 and installed rc-vacation plugin and find error below and checked no any database entry is inserted into DB.

PHP Warning: Invalid argument supplied for foreach() in : DB Error: [1292] Incorrect datetime value: '1480377600' for column 'activefrom' at row 1 (SQL Query: INSERT INTO vacation (email,domain,subject,body,created,active,activefrom,activeuntil)
VALUES ('[email protected]','xxx.xxx','Out of office','I'm currently out of office.',NOW(),'1','1480377600','1481328000')) in /usr/local/www/roundcube/program/lib/Roundcube/rcube_db.php on line 539 (POST /?_task=settings&_action=plugin.vacation-save)
Warning: Call to deprecated function rcmail_overwrite_action(); See bc.inc for replacement
Warning: Call to deprecated function Q(); See bc.inc for replacement
Warning: Call to deprecated function rcube_html_editor(); See bc.inc for replacement

any way could I fix it ?

I think not. As far as I can tell from looking at the code, this plugin is too old for that, and still uses the old RC plugin API...
