Attributes file is not being reflected on node configuration

Hello,

I created attributes file with override statement for chef-client which is not being reflected on node during runtime. Attribute file is below

force_override['chef_client']['interval'] = '180'

I know for sure it's being processed since I write out value of that attribute to log file but Windows service does not pick up that change. (Chef::Log.info("interval is set to " + node['chef_client']['interval']))

2016-05-20T05:13:37-07:00] INFO: interval is set to 180
....
[2016-05-20T05:14:15-07:00] INFO: Next chef-client run will happen in 1800.33304049832 seconds
