eh? We've got sub-second resolution, why not keep it?<BR><BR>

<BR><BR>"The times in the <B>timeval</B> structure are measured in seconds and microseconds since the Epoch, although rounding toward the nearest second may occur."<BR>
<BR>
<BR>
Rounding may occur, but won't necessarily.<BR>
Are there systems that fail if tv_usec != 0?<BR>
<BR>
<BR>
This is what TimePosix.ToUtime is for, eh?<BR>
<BR>
<BR>
I was looking to see if I could remove Usysdep.struct_timeval, as part of reducing/eliminating Usysdep.<BR>
<BR>
The opengroup link says to use utime() instead of utimes() for portability?<BR>
True? I'm skeptical.<BR>
