From: Adhemerval Zanella <azanella@sourceware.org> To: glibc-cvs@sourceware.org Subject: [glibc/azanella/y2038] time: Add 64 bit time support for getdate Date: Fri, 5 Mar 2021 19:21:07 +0000 (GMT) [thread overview] Message-ID: <20210305192107.9004A389782F@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=d4371f6c7bc0aee7eb4e0dcdaa46b044f32386b0 commit d4371f6c7bc0aee7eb4e0dcdaa46b044f32386b0 Author: Adhemerval Zanella <adhemerval.zanella@linaro.org> Date: Tue Mar 2 09:02:02 2021 -0300 time: Add 64 bit time support for getdate The getdate is basically a wrapper localtime and mktime. The 64 bit time support is done calling the 64 bit internal functions, there is no need to add a new symbol version. Checked on x86_64-linux-gnu and i686-linux-gnu.
