[PATCH] making ngx_http_parse_time support 1 digit day

[Wandenberg Peixoto]

Hello!

I was checking a strange behavior when parsing dates coming from different
browsers with this function and observed that it not supports dates with
only one digit, it expect that the date comes with 01, 02, 03 ...
But as rfc822 and rfc2822 says the day can be 1, 2 , 3, ... 10, 15, ...
So I am proposing this patch to be compliant with the rfc.

I expect that this patch could be applied to nginx code.
