From df4289508a3a0e345a87544ee4eea8cbb4c9d197 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Wed, 22 Apr 2020 01:01:21 +0200 Subject: y2038: Introduce struct __ntptimeval64 - new internal glibc type This type is a glibc's "internal" type to get time parameters data from Linux kernel (NTP daemon interface). It stores time in struct __timeval64 rather than struct timeval, which makes it Y2038-proof.
