Issue #7276 has been updated by jonforums (Jon Forums). This still fails as of r38131 on my Win7 32bit system. Given Shirosaki-san's comment, what's preventing this from being quickly fixed on trunk? Since this bug is not made visible by the rubyinstaller CI (build slave location) I will manually run any tests or builds you need in order to validate the fix. Let me know what you need. ---------------------------------------- Bug #7276: TestFile#test_utime failure https://bugs.ruby-lang.org/issues/7276#change-34290 Author: jonforums (Jon Forums) Status: Assigned Priority: Normal Assignee: nobu (Nobuyoshi Nakada) Category: core Target version: 2.0.0 ruby -v: ruby 2.0.0dev (2012-11-04 trunk 37467) [i386-mingw32] I'm currently travelling and am in UTC-5. I get the following `make test-all` failure on Win7 32bit with mingw-w64 gcc 4.7.2. It appears that trunk@37467 is not handling daylight savings time correctly. I'm not going to have time to try to repro on my Arch system, but can anyone else in UTC-5 (or other DST observing region) repro on either a Win7 or Linux system?
