        setScheduleExpression(scheduleExpression);
        return this;
    }
<p>
A cron expression that describes details about the monitoring schedule.
</p>
<p>
The supported cron expressions are:
</p>
<ul>
<li>
<p>
If you want to set the job to start every hour, use the following:
</p>
<p>
<code>Hourly: cron(0 * ? * * *)</code>
</p>
</li>
<li>
<p>
If you want to start the job daily:
</p>
<p>
<code>cron(0 [00-23] ? * * *)</code>
</p>
</li>
<li>
<p>
If you want to run the job one time, immediately, use the following keyword:
</p>
<p>
<code>NOW</code>
</p>
</li>
</ul>
<p>
For example, the following are valid cron expressions:
</p>
<ul>
<li>
<p>
Daily at noon UTC: <code>cron(0 12 ? * * *)</code>
</p>
</li>
<li>
<p>
Daily at midnight UTC: <code>cron(0 0 ? * * *)</code>
</p>
</li>
</ul>
<p>
To support running every 6, 12 hours, the following are also supported:
</p>
<p>
<code>cron(0 [00-23]/[01-24] ? * * *)</code>
</p>
<p>
For example, the following are valid cron expressions:
</p>
<ul>
<li>
<p>
Every 12 hours, starting at 5pm UTC: <code>cron(0 17/12 ? * * *)</code>
</p>
</li>
<li>
<p>
Every two hours starting at midnight: <code>cron(0 0/2 ? * * *)</code>
</p>
</li>
</ul>
<note>
<ul>
<li>
<p>
Even though the cron expression is set to start at 5PM UTC, note that there could be a delay of 0-20 minutes from
the actual requested time to run the execution.
</p>
</li>
<li>
<p>
We recommend that if you would like a daily schedule, you do not provide this parameter. Amazon SageMaker will
pick a time for running every day.
</p>
</li>
</ul>
</note>
<p>
You can also specify the keyword <code>NOW</code> to run the monitoring job immediately, one time, without
recurring.
