I should probably be embarrased to ask this, but I'll do it anyway :-)

Where are the these functions declared?  I grep'ed /usr/include and /usr/include/sys
and couldn't find anything....

Any info is much appreciated,
Tom

Interesting. On my SunOS 4.1.3 station (I assumed that you were looking
on Solaris 2.x based on the newsgroup this post of yours is in), the
man page page implies that gettimeofday should be in the directory
/usr/include/sys/time.h, and utimes should be in /usr/include/sys/types.h
but I could not find it declared in any of the .h files in the entire
/usr/include tree either (went looking with find)!

...or, at least, you inferred that from the man page.

The #includes in UNIX man page SYNOPSIS sections for functions
unfortunately aren't guaranteed to declare the function itself; they may
merely define the data types used in the arguments to the functions.

The include file <sys/time.h> defines "struct timeval", which is why
it's in the "gettimeofday()" manual page; it should also be in the
"utimes()" manual page, rather than <sys/types.h>, for the same reason,
but unfortunately the "utimes()" manual page is in error.

With the advent of function prototypes, hopefully UNIX systems will,
over time, clean up their acts and have declarations for *all* the
functions in their APIs.
