Reland of [date] Add ICU backend for timezone info behind a flag (patchset #1 id:1 of https://codereview.chromium.org/2811103002/ ) Reason for revert: Reland with tests marked as off in no-i18n mode Original issue's description: > Revert of [date] Add ICU backend for timezone info behind a flag (patchset #17 id:320001 of https://codereview.chromium.org/2724373002/ ) > > Reason for revert: > Breaks noi18n: > https://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20noi18n%20-%20debug/builds/13314 > > Original issue's description: > > [date] Add ICU backend for timezone info behind a flag > > > > This patch implements a timezone backend which is based on ICU, rather > > than operating system calls. It can be turned on by passing the > > --icu-timezone-data flag. The goal here is to take advantage of ICU's > > data, which is more complete than the data that some system calls expose. > > For example, without any special code, this patch fixes the time zone > > of Lord Howe Island to have a correct 30 minute DST offset, rather than > > 60 minutes as the OS backends assume it to have. > > > > Unfortunately, the parenthized timezone name in Date.prototype.toString() > > differs across platforms. This patch chooses the long timezone name, > > which matches Windows behavior and might be the most intelligible, but > > the web compatibility impact is unclear. > > > > BUG=v8:6031,v8:2137,v8:6076 > > > > Review-Url: https://codereview.chromium.org/2724373002 > > Cr-Commit-Position: refs/heads/master@{#44562} > > Committed: https://chromium.googlesource.com/v8/v8/+/b213f2399038a615cdfbfa0201cddc113d304018 > > TBR=ulan@chromium.org,jshin@chromium.org,jgruber@chromium.org,littledan@chromium.org > # Skipping CQ checks because original CL landed less than 1 days ago. > NOPRESUBMIT=true > NOTREECHECKS=true > NOTRY=true > BUG=v8:6031,v8:2137,v8:6076 > > Review-Url: https://codereview.chromium.org/2811103002 > Cr-Commit-Position: refs/heads/master@{#44565} > Committed: https://chromium.googlesource.com/v8/v8/+/13ad50811024ace5623d5d4d13cea4ef21f4affd TBR=ulan@chromium.org,jshin@chromium.org,jgruber@chromium.org,machenbach@chromium.org BUG=v8:6031,v8:2137,v8:6076 Review-Url: https://codereview.chromium.org/2813863002 Cr-Commit-Position: refs/heads/master@{#44575}
