I ran the following expecting it to provide me with the date 35 years
ago
date -d "now - 35 years"
Instead I received the error:
date: invalid date ‘now - 35 years’
Testing it further I found that the break point is at 24 years:
$ date --version

$ date -d "now - 24 years"
date: invalid date ‘now - 24 years’
$
I compiled from the latest coreutils source and found it to have
the same issue:
$ cd coreutils/src/
$ ./date --version
date (GNU coreutils) 8.32.143-62a7c

$ date -d "now - 23 years"

$ date -d "now - 24 years"
date: invalid date ‘now - 24 years’
$
I found that this did work on a system running coreutils 8.23 so
something seems to have broken since then. These are all Linux systems
that I've tried this on. The system I tested on was a fresh Ubuntu 21.04
VM.
Linux ubuntu2104 5.11.0-16-generic #17-Ubuntu SMP Wed Apr 14 20:12:43 UTC 2021

Thanks,
