For portability reason by default glpsol uses a portable version of
lib_get_time which being based on gmtime provides only 1-sec precision.
You can replace the file glplib1b.c before compiling glpk by
appropriate platform-specific version; see the subdirectory sysdep
where two versions are provided: for GNU/Linux and for W32 API.
If none of them fits for your needs, you can provide your own version.
