Both calls from GNU date are returning EINVAL. Those are Linux kernel system calls. Those Linux kernel system calls are using CLOCK_MONOTONIC.
OK, I think I understand now. For some reason Linux prohibits you from setting CLOCK_REALTIME to a value less than what CLOCK_MONOTONIC would report. I don't know why Linux has this restriction - it violates POSIX as near as I can tell - but at any rate as you say it's a problem with the Linux kernel, not with GNU 'date'.
