Isn't struct timespec standard these days?  At least if you have 
nanosleep() you also have struct timespec.

I would suggest adding something like dbi_result_get_timespec() and keep 
the dbi_result_get_datetime() for compatibility.  Also, it should not be 
impossible to make the source compile on systems where timespec is not 
available, and not providing a dbi_result_get_timespec() on these systems.
