Expires format

I have seen expires in hours (h), days (d), and max. How do I write an
expire in 30 minutes? Is there a link to resource that lists all the
expire options?

Thank you Dave, the English Wiki was missing the example you posted.

There is actually a link in the Russian wiki page Dave linked to above.
The link is on the word time, and it lists the syntax for the time
format that can be used for expires.

The English wiki needs this added.

All the best,

expires 30m;

I’m extrapolating this from
http://translate.google.com/translate?js=y&prev=_t&hl=en&ie=UTF-8&layout=1&eotf=1&u=http://sysoev.ru/nginx/docs/http/ngx_http_headers_module.html&sl=ru&tl=en

which gives an absolute example as

expires @15h30m;
