touch raises panic when running with QEMU for arm64

Affected images versions

v2024dev3

Unaffected images versions

Older versions

Background

After merging pkg/rust-coreutils!27 (merged) bootstrap process in arm64 and armhf fails with

2023/08/08 00:50:06 debootstrap.log | thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: IndeterminateOffset', /usr/src/packages/BUILD/src/uu/touch/src/touch.rs:89:72

2023/08/08 00:50:07 debootstrap.log | Aborted

After testing the different changes in the MR, the cause of the issue is:

In order to locally reproduce the issue:

• Download an older Fixed Function OSpack
• Use systemd-nspawn to chroot into it
• Install the new rust-coreutils
• run touch tmpfile to create a new file
• run touch tmpfile to update the file, this will trigger the issue

Root cause

The code that raises the error is here with:

local_dt_to_filetime(time::OffsetDateTime::now_local().unwrap())

which tries to return the local time taking into account timezone offset is here with:

local_offset_at(datetime).ok_or(error::IndeterminateOffset)

Reproducibility

How often the issue is hit when repeating the test and changing nothing (same device, same image, etc.)?

Put the ✅ in the most appropriate entry:

1. ✅ always
2. often, but not always
3. rarely

Impact of bug

This bug prevents bootstraping process to complete, causing all the images for arm64 and armhf to fail in the development release v2024dev3

Outcomes

• pkg/rust-coreutils!29 (merged)
