Actually, BSD being an AT&T-derived system, things aren't that bad.

BSD still has the original V7-flavored "utime()" call, with the second
argument a pointer to the first element of an array of 2 "time_t"s
(that's right, "utime()" in BSD has no microseconds-field support). 

Somewhere in the "USG UNIX" chain, the structure was introduced; on most
systems, the structure has the same memory layout as the array.

4.2BSD introduced a call named "utimes()" - note the "s" - that takes a
pointer to an array of 2 "struct timeval"s; that's the call that
supports microseconds fields.  Too bad the 88Open folks didn't pay
attention to this, and just called their call that supported
microseconds fields "utime()"....
