This formatter https://github.com/llvm/llvm-project/pull/78609 was originally passing the signed seconds (which can refer to times in the past) with an unsigned printf formatter, and had tests that expected to see negative values from the printf which always failed on macOS. I'm not clear how they ever passed on any platform. Fix the printf to print seconds as a signed value, and re-enable the tests. >From 4477bfb879c461253e62212011497da205a7ed74 Mon Sep 17 00:00:00 2001 From: Jason Molenda <jmole...@apple.com> Date: Wed, 7 Feb 2024 18:13:14 -0800 Subject: [PATCH] [lldb] Fix printf formatting of std::time_t seconds This formatter https://github.com/llvm/llvm-project/pull/78609 was originally passing the signed seconds (which can refer to times in the past) with an unsigned printf formatter, and had tests that expected to see negative values from the printf which always failed on macOS.
