Cron entry quandry

[Scott Gerhardt <scott_(_at_)_g-it_(_dot_)_ca>]

I can't figure out why the following cron entry does not work.  The 
lines have been wrapped for email.
I typically create separate script files but this one was simple enough 
for a one liner.

*/1     *       *       *       *       /usr/local/bin/mysqldump 
--all-databases | /usr/bin/gzip \
> /home/hsas_db_backups/hsas_DB_backup_`/bin/date 
"+%Y-%m-%d_%H:%M:%S"`.sql.gz


I keep getting the following error which seems like the line is being 
truncated at just after the `+'.  Is there some limitation to line 
length in crontab?  I happen to be running 3.5 Release on this 
particular box.

ERROR:
