Add an enum argument to DateTimeConfigurationChangeNotification to
control whether or not to redetect the host time zone. The default value
kSkip doesn't cause redetecting so that callers do not need to change if
they want the current behavior (e.g. Chromium).
Note that the host time zone detection does not work when v8 is run
inside a sandbox as in Chromium so that Chromium detects the host time
zone outside the sandbox before calling
DateTimeConfigurationChangeNotification. OTOH, other v8 embedders may
find it more convenient for v8 to do the host time zone detection on
their behalf. In that case, they can call the function with the new
argument set to value kRedetect.
Test:
With PHP+V8Js on linux, execute:
php -r '
putenv("TZ=Europe/Helsinki");
$v8 = new V8Js();
$v8->executeString("print((new Date(0)).toString()+\"\\n\");");
putenv("TZ=America/New_York");
$v8->executeString("print((new Date(0)).toString()+\"\\n\");");'
