I think this is a good idea.  I just finished a clean install of
5.2-RC2 on my ultra-10, and I'm building a few of my favorite
ports on that.  I'll then duplicate that install to alternate
partitions, and see what happens when updating that to a 64-bit

So, all I need to change is the line:
    typedef	__int32_t	__time_t;

in /usr/src/sys/sparc64/include/_types.h
and the line:
    long		tv_sec;		/* seconds (XXX should be time_t) */

in /usr/src/sys/sys/_timeval.h

Most the other definitions of tv_sec that I found are
already using time_t.  Btw, I noticed:
     u_int32_t		timestamp;	/* tv_sec of last match*/
     long		timestamp;	/* timestamp (tv_sec) of last match */

but I haven't looked at the code to see how much we care about
those two references.

Anything else, Harti?
