Can't parse date when running

• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've included all information below (version, config, etc).
• Yes, I've tried with the standalone linter if available. (https://golangci-lint.run/usage/linters/)

Description of the problem

When running golangci-lint run -E gofmt I am shown an error:

WARN [linters context] structcheck is disabled because of go1.18. You can track the evolution of the go1.18 support by following the https://github.com/golangci/golangci-lint/issues/2649.

Hey, thank you for opening your first Issue ! 🙂 If you would like to contribute we have a guide for contributors.

Hello,

can you provide your git configuration?
and the information of the diff installed on your system?

[J4cku]

diff --version

It feels like your diff doesn't follow the specification for the timestamp format
https://www.gnu.org/software/diffutils/manual/html_node/Detailed-Unified.html

[BorzdeG]

@ldez But the date can be shown without a timezone.

I have a similar error:
can't parse patch: parsing time \"2022-08-24 14:35:19\" as \"2006-01-02 15:04:05 -0700\": cannot parse \"\" as \"-0700\""

[ldez]

The specification seems clear: the timezone is not optional.

The timestamp looks like ‘2002-02-21 23:30:39.942229878 -0800’ to indicate the date, time with fractional seconds, and time zone. The fractional seconds are omitted on hosts that do not support fractional timestamps.

I will try to find how to handle diff command that doesn't follow this spec.

[BorzdeG]

Created an issue in the library where the error occurs: sourcegraph/go-diff#64

[BorzdeG]

Running tests on macOS gives the same error:

With your permission, I'll dig further with this issue

[ldez]

The problem comes from the diff output.

Our CI runs a job on macOS/darwin.

go-diff has a pattern that follows GNU diff.

For me it's a problem with Apple diff.

[J4cku]

Any idea how to install different diff?

[shepherdjerred]

brew install diffutils worked for me.
