A problem occurs when the input time of the DATE function is passed to the database! Expert guidance!

My code is as follows:

$ Date = date ("Y-m-d H: I: s ");
$ Conn = new mysqli ('localhost', 'root', '123', 'time ');
If (mysqli_connect_errno ()){
Echo 'cannot connect to the database. ';
Exit ();
}
Echo $ date;
$ Query = "insert into time values (null, $ date )";
$ Re = $ conn-> query ($ query );
If (! $ Re ){
Echo 'failed to input data! ';
Exit ();
}
Echo 'successfully ';
$ Conn-> close ();
?>

Always show failed

Error message:
Debug Strict (PHP 5): C: \ Program Files \ Apache Software Foundation \ Apache2.2 \ htdocs \ timetest. php line 2-date () [function. date]: It is not safe to rely on the system's timezone settings. please use the date. timezone setting, the TZ environment variable or the date_default_timezone_set () function. in case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. we selected 'utc' for '8. 0/no DST 'Instead

Thank you for your advice!
