Absolute rather than relative times in expires directives

[rgrraj]

Hi

Thank you all for  the suggestions and thoughts. 

I did double check the nginx version I am having and it is 1.9.2. 
root at ser2:~# nginx -V
nginx version: nginx/1.9.2
built by gcc 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) 
configure arguments:
--add-module=/tmp/nginx/ngx_http_substitutions_filter_module-master
--add-module=/tmp/nginx/headers-more-nginx-module-0.26
--add-module=/tmp/nginx/ngx_pagespeed-release-1.9.32.3-beta
--sbin-path=/usr/local/sbin/nginx --conf-path=/etc/nginx/nginx.conf
root at ser2:~# 

but when I use the expires directive it shows invalid error same as before.

Seems like to get the feature I need to update the nginx version.

Thanks
Govind
