My PHP code needs to set the if_modified_since header, but to set it, it needs to consider two times, one of it's data source, but also of a configuration file that is only known to the Apache C Module. Already I am passing a number of variables to the PHP code via the r->subprocess_env, and I would now like to also pass the apr_finfo_t.mtime of the config file, but in a format that PHP can understand. In the PHP code, I am going to be using filemtime() which returns a Unix timestamp.
How can I convert apr_finfo_t.mtime into a Unix timestamp? Sam
