-- f4e870453d02106c2685e0461816469a4704ad25 by Abseil Team <absl-team@google.com>: Expose TimeZone::NextTransition() and PrevTransition() now that we have absl::CivilSecond support in time.h. Note that these are for informational purposes only. General time code should not care when offset changes occur. PiperOrigin-RevId: 217177292 -- cfadd275c7333f7c27c4d682b9d167010d874e69 by Abseil Team <absl-team@google.com>: Import of CCTZ from GitHub. PiperOrigin-RevId: 217153577 -- 6ff5b8c61a1239b9c0478a7c62bcd2844b310307 by Jon Cohen <cohenjon@google.com>: Fix code examples in hash_testing.h. Includes random clang-format changes. PiperOrigin-RevId: 216898995 -- de124129d27f4627dabe193a10bf106a11783fba by Shaindel Schwartz <shaindel@google.com>: Add contribution guidelines describing how we decide whether to include an API in Abseil.
