Raw Blame History

From 47999bb8735f653f06e0eb46e7eced600210b9da Mon Sep 17 00:00:00 2001
From: Greg Hudson <ghudson@mit.edu>
Date: Sat, 29 Apr 2017 17:30:36 -0400
Subject: [PATCH] Add timestamp tests
Add a test program for krb5int_validate_times() covering cases before
and across the y2038 boundary. Add a GSSAPI test program to exercise
lifetime queries, and tests using it in t_gssapi.py for ticket end
times after y2038. Add a new test script t_y2038.py which only runs
on platforms with 64-bit time_t to exercise end-user operations across
and after y2038. Add an LDAP test case to test storage of post-y2038
timestamps.
ticket: 8352
(cherry picked from commit 8ca62e54e89e2fbd6a089e8ab20b4e374a486003)
