[keen osprey]

https://man7.org/linux/man-pages/man3/errno.3.html

ETIME  Timer expired (POSIX.1 (XSI STREAMS option)).

              (POSIX.1 says "STREAM ioctl(2) timeout".)

or, if you prefer:
https://kernel.googlesource.com/pub/scm/linux/kernel/git/nico/archive/+/v0.97/include/linux/errno.h#65
