That's the expected result on 32-bit hardware platforms. You normally need a 64-bit platform (or a rather sophisticated 32-bit platform with 64-bit time_t's) to do this test. I have changed that error message to be more informative. A 32-bit time_t is not adequate to represent the extremely large date ranges used for these tests. Note, this is a fundamental limitation in the time_t argument of the gmtime and mktime routines in the C library that are used to test libqsastime in qsastime_testlib. There is no such time_t size limitation in libqsastime which is designed to work happily with 32-bit ints and 64-bit doubles (the usual sizes on both 32-bit and 64-bit hardware). So libqsatime should be okay on your system for large date ranges. However, it would still be nice to find a Windows system with 64-bit time_t's (for the C library comparison routines) and the usual 32-bit ints, and 64-bit doubles that gives a good result for qsastime_testlib. That would be a useful confirmation of the good results we have for that combination of sizes in Linux. Of course, the most important point is you have found a way to make windows build again with your recent commit. Thanks! Alan __________________________ Alan W.
