When scheduling a report to run, on the cron expression page:

1. It would be nice if there was bit of javascript on the page which could auto-generate the expression. Display a menu of commonly used period points, (everyday at midnight, first of the month, first of the week, first of the year, etc...) and then when selected, update the cron expression field.

2. In the report-configuation.xml, there is a blurb of text:

http://quartz.sourceforge.net/javadoc/org/quartz/CronTrigger.html
Field Name Allowed Values Allowed Special Characters
Seconds 0-59 , - * /
Minutes 0-59 , - * /
Hours 0-23 , - * /
Day-of-month 1-31 , - * ? / L W C
Month 1-12 or JAN-DEC , - * /
Day-of-Week 1-7 or SUN-SAT , - * ? / L C #
Year (Opt) empty, 1970-2099 , - * /

It would be nice if the page displayed some kind of text to help the user fill in the field appropriately.
