date: fails to parse "next monday"

[jfinkels]

Environment: Ubuntu 24.04, uutils main branch (git commit 3971bb3), GNU coreutils v9.6.38-2b088-modified

Steps to reproduce:

date -d "next monday"

What happens now: uutils date fails with error message:

date: invalid date 'next monday'

What I expected to happen: GNU date succeeds with

Mon Apr  7 12:00:00 AM EDT 2025

(That's midnight on the next Monday following the time of writing this issue.)

Notes: this is causing a failure in GNU test file tests/date/date-next-dow.pl. The underlying issue is uutils/parse_datetime#127.

Is this a uutils issue or a chrono issue?

in date.rs line 230 we use checked_add_signed, which I think is where the test is failing from.

DateSource::Human(relative_time) => {
                // Double check the result is overflow or not of the current_time + relative_time
                // it may cause a panic of chrono::datetime::DateTime add
                match now.checked_add_signed(relative_time) {
                    Some(date) => {
                        let iter = std::iter::once(Ok(date));
                        Box::new(iter)
                    }
                    None => {
                        return Err(USimpleError::new(
                            1,
                            format!("invalid date {relative_time}"),
                        ));
                    }
                }
            }
