Never retreat :)

I shared your sentiment months ago, until I considered that 90%
of our applications are 35 minutes or less.  I'd suggest something
less dramatic, two types:


Meaning, respectively, +-35 min, or several milleneia, at the
programmers choice.  Have two implementations of ap_time_diff()
or whatever, one short, one long.  Nearly every APR function
needs to deal in minutes, not days.  For httpd and other users,
provide both types.
