Hi, after upgrading to latest v8 from master (say, v4.10.43) on linux
(ubuntu 15.10) and os x (10.11.3) changing timezone with
putennv("TZ=<timezone>")
(http://man7.org/linux/man-pages/man3/putenv.3.html) new timezone affects
v8 runtime without calling
v8::Date::DateTimeConfigurationChangeNotification. I guess it happens after
"[runtime] Migrate several Date builtins to C++"
(https://github.com/v8/v8/commit/065e9c536f14b3d7cb4d140c6f74e024e31ee1a2)
commit.
Here is some meta-code to demonstrate problem:
putenv("TZ=America/New_York");
v8::Date::DateTimeConfigurationChangeNotification();
v8::MaybeLocal<v8::Date> date = v8::Date::New(context, 1445444940000.0).
ToLocalChecked();
date.ToLocalChecked()->ToString(context); // Wed Oct 21 2015 09:29:00
GMT-0700 (EDT)
putenv("TZ=UTC");
date.ToLocalChecked()->ToString(context); // Wed Oct 21 2015 09:29:00
GMT-0700 (UTC)
before (apr. that changes I mentioned above) both ToString() returned EDT
time.
Based on this, I have few questions:
1. How now TZ changes handled internally, if any?
2. What is recommended way to handle TZ changes?
3. Is using v8::Date::DateTimeConfigurationChangeNotification() still
mandatory to notify TZ changes?
