I ran into this just this afternoon, and I am still looking for an 
answer, but what I have found may be helpful.

What I found is that there is an apr_time_ansi_put converts a time_t to 
an apr_time_t, but the only thing that may convert the apr_time_t into 
the number of seconds since Jan 1st 1970 is apr_time_sec(apr_time_t) .

With you looking to set a header (a text string), you may want to 
consider using apr_rfc822_date() to take the apr_finfo_t.mtime and turn 
it directly into a string and then just set the header to that value.
