this patch allows you to disable splay by setting value to 0 (without patch you get division by zero error)
i use load spreading by ip address, so i do not want extra sleep because the "spreading" is sufficent
# disable spay and use pseudo randomize: take minute to run from ip address last octet
default['chef_client']['cron']['minute'] = node['ipaddress'].split('.').to_i % 59
default['chef_client']['cron']['hour'] = '*'
default['chef_client']['splay'] = 0
