Schedule job for specific time once per day

Shaun, your link above is to a user profile, not a module. I assume you meant to reference a module?

Anyways, I'd like to achieve the exact same thing, with job_scheduler, so that my scheduled task is portable with the database.

Here's what I've got. I'd like to use the cron functionality, as it seems the most straight forward method to do something only once a day

<?php

// Building the scheduler seems to be straightforward enough, based on the readme.txt
function hook_cron_job_scheduler_info() {
  $schedulers = array();
  $schedulers['custom'] = array(
    'worker callback' => custom_job',
    'jobs' => array(
         array('crontab' => '0 0 * * *', 'periodic' => TRUE),
      )
  );
  return $schedulers;
}

// The actual job I'm doing is totally arbitrary. Shouldn't matter to job_scheduler, and it doesn't
function custom_job() {
  $job = db_truncate('custom_table')
  ->execute();

  return $job;
}
?>

The problem is that my job, which is scheduled using 'crontab', is firing on every cron run, instead of the cron specified with '0 0 * * *'. I imagine I've overlooked something rather simple, but the documentation is not terribly clear on how to do this.

I'd love some feedback on this, as it seems like the slickest and safest way to do a scheduled task. I'd rather avoid writing a custom crontab, and then hooking that. This is what job_scheduler was built for, right?

Closing this since the original poster closed it.

@killtheliterate, that sounds like a bug. Please open a new issue if you're still having problems. Thanks.
