From f23cef6f66a44c5c1cc8717f74b658d14fde04e5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ingo=20Kl=C3=B6cker?= Date: Mon, 5 May 2025 16:14:55 +0200 Subject: [PATCH 4/4] cpp: Ensure correct expiration time on 32-bit arch with 64-bit time_t * lang/cpp/src/key.cpp (Subkey::expirationTime): Cast away the signedness of _gpgme_subkey.expires before casting to time_t. -- _gpgme_subkey.expires stores the expiration as `long int` although the expiration is always an unsigned value. Casting the value to unsigned long int before casting it to time_t ensures that we get the correct expiration value for 64-bit time_t even on 32-bit systems. With signed 32-bit time_t we still get a negative value as before.
