From c40e42d4c940db4d03f51cd253a246ed5bb30787 Mon Sep 17 00:00:00 2001 From: Alexander Zhirov Date: Thu, 13 Jun 2024 15:06:14 +0300 Subject: [PATCH] Some libc implementations are shifting toward using 64-bit time_t for all arches to solve the year 2038 problem. musl is one of them, see [1]. So when compiling for a 32-bit arch time_t will be long long. This commit adds this option.
