JoeKuan <kuan....@gmail.com> added the comment: I don't think it is to do with the underlying C mktime. Because it works fine with 00:59:58 and 01:00:00, 1, Jan 1970. It is to do with some specific value -1 in the internal code of time.mktime
Here is the C code. int main(int argc, char *argv[]) { struct tm aTime = { 58, 59, 0, 1, 0, 70, 0, 0, 0, 0 }; time_t mTime = mktime(&aTime); printf("%s\n", ctime(&mTime)); aTime.tm_sec = 59; mTime = mktime(&aTime); printf("%s\n", ctime(&mTime)); aTime.tm_sec = 0; aTime.tm_min = 0; aTime.tm_hour = 1; mTime = mktime(&aTime); printf("%s\n", ctime(&mTime)); } ------------------------------------------------------- Output from the same machine which gives the python error message Thu Jan 1 00:59:58 1970 Thu Jan 1 00:59:59 1970 Thu Jan 1 01:00:00 1970 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11850> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
