Cron job syntax on Google App Engine

Question

Hello
I am trying to schedule a job to run "every 15 minutes on weekdays only" using the Google App Engine cron scheduler (for Java apps). http://code.google.com/appengine/docs/java/config/cron.html#The_Schedule_Format
Does any know what the correct syntax is? I have tried using the xml below, but find that it runs on all days not just the weekdays listed.

<?xml version="1.0" encoding="UTF-8"?>
<cronentries>
  <cron>
    <url>/finance/collect</url>
    <description>Fetch data every 15 minutes</description>
    <schedule>every 15 minutes monday, tuesday, wednesday, thursday, friday</schedule>
  </cron>
</cronentries>

Thanks

Answer 1

According to the documentation, once you specify days you can only specify a single absolute time for the task to run.

I suggest you check the day of week in your job and do nothing if it is not a weekday.

Answer 2

According to your link it appears the only difference is the fact that you have a space in the schedule tag between the selectors and this example does not:

2nd,third mon,wed,thu of march 17:00

Answer 3

How to config a task to run every 5 minutes between 9:00am~20:00pm, but every 10 minutes in other time of the day.
