cron recipe error

[Chris Dawson]

5 1 * * 0 /home/cdawson/script.rb > /home/cdawson/`date "+%Y-%m-%d"`.log

I want this to run on Sundays at 1:05 am. The script is executable. 
It doesn't seem to run, and nothing is logged in the log file.  Any
idea why?

I think that I tried things like:

5 1 * * sun /home/cdawson/script.rb > /home/cdawson/`date "+%Y-%m-%d"`.log

But this didn't work either.  After reading the man page, maybe "sun"
was capitalized.  Can anyone tell me the correct recipe?

Either way, it seems like the first one should run.  Man page says "0
or 7 is Sun..."

Thanks,
Chris
