Feature -- as it should be, in fact.
If you look at what the BSD man-pages say about it,
they say "will alter time in future version" -- Linux
does it :-)
I have uses for code where I don't need to query system
time just because I want to know how much time has elapsed
in the select() -- clean timeout is obvious, but when I
have select on fd, and I want to know how long it has been
waited for...
