 * Since upgrading both WordPress to v.3.3 and the Twentyten theme, the date and
   time fields have disappeared from the Session admin page (both edit and add).
 * Explanation and/or fix anyone?
 * I have tried reinstalling to no avail.

 * For what it’s worth, the session date/time admin problem is with WordPress 3.3—
   it works as intended with 3.2

 * I am a WordPress newbie, but It appears this problem is due to the way add_meta_box
   is being done. For version 0.5.2 conference-schedule.php on line 84 there is 
   the line:
 * `$this->add_meta_box( 'cs_schedule_metabox', __( 'Schedule', $this->name ), '
   schedule_metabox', 'session', 'normal', 'core' );`
 * Take that line and move it to the admin_init function on line 278. Then it will
   show up again. At least it does for me.
 * I think this is related to this issue: [http://wpdevel.wordpress.com/2011/12/07/do-not-include-wp-adminincludestemplate-php-to-get-add_meta_box/](http://wpdevel.wordpress.com/2011/12/07/do-not-include-wp-adminincludestemplate-php-to-get-add_meta_box/)

 * Indeed… that fixes the problem.
 * Many thanks for taking the time to research and resolve it!

 * Thank you for sharing this fix! It worked for me on two different sites.
