As reported by Oleksij Rempel here

the representation of timeval timestamps are signed values which leads to
negative values on 32 bit machines addressing the year 2038 unix sec counter
overflow.
Fix the issue on 32 bit systems by converting the timeval values to unsigned
ASCII value representations.

In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115
the asm-generic/sockios.h header no longer defines SIOCGSTAMP.
Instead it provides only SIOCGSTAMP_OLD.
The linux/sockios.h header now defines SIOCGSTAMP using either
SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. This linux only
header file is not pulled so we get a build failure.
canlogserver.c: In function 'main':
canlogserver.c:404:21: error: 'SIOCGSTAMP' undeclared (first use in this function); did you mean 'SIOCGRARP'?
if (ioctl(s[i], SIOCGSTAMP, &tv) < 0)
^~~~~~~~~~
SIOCGRARP
canlogserver.c:404:21: note: each undeclared identifier is reported only once for each function it appears in
