[Bug-wget] wget -N timestamp sometimes off by one second

User-agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.28) Gecko/20120313 Thunderbird/3.1.20

Version: 1.13.4
Operating System: OpenWrt 10.03.1
Kernel: Linux 2.6.32.27
Filesystem: vfat

What happens is that wget -N writes a filestamp that is one second
earlier than the Last-modified HTTP header and therefore when invoked
again, downloads the same file again even though it should not. So, the
timestamp it uses for comparison is right, but the one that ends up
written on the filesystem is wrong.

It's not even consistent, with most files it works okay, but for some,
it does not work. So far, I did not manage to find any pattern in those
files that end up mis-timestamped.
