From 504c98717062cb9bcbd4b3e59e932d04331ddca5 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Thu, 16 Jan 2020 23:40:51 +0100 Subject: [PATCH] y2038: Introduce struct __timeval64 - new internal glibc type This type is a glibc's "internal" type similar to struct timeval but whose tv_sec field is a __time64_t rather than a time_t, which makes it Y2038-proof. This struct is NOT supposed to be passed to the kernel - instead it shall be converted to struct __timespec64 and clock_[sg]ettime syscalls shall be used (which are now Y2038 safe).
