Bug 1709867 - Add a ICU-only DateTimeInfo::timeZoneId method. r=anba,platform-i18n-reviewers,dminor

Differential Revision: https://phabricator.services.mozilla.com/D169611

The Bugbug bot thinks this bug should belong to the 'Core::Gecko Profiler' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

:tschuster, since you are the author of the regressor, bug 1709867, could you take a look? Also, could you set the severity field?

For more information, please visit auto_nag documentation.

This is most likely a fallout from Bug 1776694 instead. I will look at it.

Set release status flags based on info from the regressing bug 1776694

Hi Petr, thanks for filing the bug.
Unfortunately I don't have access to a Solaris machine. I created a patch, but could you help me verify that it fixes the issue on your end?

It seems that the patch helps. But since there seems to be other two issues I wasn't able to fully build Firefox yet.

One of other issues is 1822980. This is reason of wrong bestion.

Fwiw, seeing the same regression on OpenBSD (cf log at http://buildbot.rhaalovely.net/nine/#/builders/3/builds/1627/steps/8/logs/stdio)

will report later if the patch helps, thanks

my build with https://phabricator.services.mozilla.com/D172846 is green: http://buildbot.rhaalovely.net/nine/#/builders/3/builds/1628
so that fixes the regression for me.

Thank you both for verifying the patch, and sorry about the issue. I asked for a review now and hopefully will land it quickly.
