Debugger rewrites date-times being passed through the args array

[jeremy-rifkin]

Does this issue occur when all extensions are disabled?: I need to use the C++ extension but it appears this bug does not occur within the C++ extension.

• VS Code Version: 1.96.4
• OS Version: Macos, linux, windows, multiple versions

Steps to Reproduce:

1. Open a folder in vscode
2. Add a simple entry to launch.json passing a timestamp like 2025-01-16T14:30:00.0Z, e.g.

        {
            "name": "bug repro",
            "type": "cppdbg",
            "request": "launch",
            "program": "/bin/echo",
            "args": ["2025-01-16T14:30:00.0Z"],
            "cwd": "${workspaceFolder}",
            "MIMode": "gdb",
            "miDebuggerPath": "/usr/bin/gdb",
        },

3. Observe the program be passed 01/16/2025 14:30:00

Somehow vscode is silently rewriting my argument.

I briefly stepped through a local build of vscode ealier and this does not appear to be done in the C++ extension.

I was debugging a program earlier which requires a specific timestamp format and this vscode bug made it impossible for me to debug my program in the IDE.

it appears this bug does not occur within the C++ extension.

Are you sure? I don't see this with node, only c++, and I'd expect they are parsing the args strangely. microsoft/vscode-cpptools#13241

I am not sure. I spent some time debugging a local version of vscode and it appeared to originate in vscode not the extension. I can report to vscode-cpptools. nvm I see that has already been done.
