First of, you're wrong; at least with settimeofday() - that is no POSIX
function, it's a proprietary BSD extension.
Have a look at:
http://www.opengroup.org/onlinepubs/007904975/toc.htm
to see what functions are part of POSIX and are sensitive to be added
into our repository (if they are missing).
Although we are okay supporting some BSD extensions, I don't think
settimeofday() should be one of those. So I'd say either use the GNU
date as Be did, or port it over to be Be native (and lose simple
updates that way).
Since these applications aren't changed that often anymore, I don't
care about a particular way between these two. Using GNU date might be
less effort, though.
Bye,
Axel.
