After the install Magento2 on localhost, its working file. But when I try to re-index, its getting the following error.

Fatal error: Call to a member function format() on null in /var/www/html/magento2/lib/internal/Magento/Framework/Stdlib/DateTime/Timezone.php on line 260

Have any idea for this?

@supravatweb, the issue was fixed in 1.0.0-beta. Please, check the issue on this version.

Problem still exists on my side on certain server/php, CentOS with php 5.5.24 to be exact. Intl version 1.1.0, ICU version 4.2.1. Everything is working on Windows and Ubuntu with latest 5.5.x php, so it's most likely usual problem when different/older intl is behaving differently.

In my case IntlDateFormatter excepts this:
object(DateTimeZone)#3271 (2) {
["timezone_type"]=>
int(3)
["timezone"]=>
string(15) "Europe/Belgrade"
}

But crashes on this:
object(DateTimeZone)#3271 (2) {
["timezone_type"]=> int(1)
["timezone"]=> string(6) "+00:00"
}
Fatal error: Call to a member function format() on a non-object in /home/magento2/public_html/lib/internal/Magento/Framework/Stdlib/DateTime/Timezone.php on line 261

It seems it only excepts DateTimeZone with timezone identifier.

One more thing, it's possible last fallback added in 1.0.0-beta is also wrong:
$timezone ?: $date->getTimezone() ?: new \DateTimeZone(\DateTimeZone::UTC),

new \DateTimeZone(\DateTimeZone::UTC)
Fatal error: Uncaught exception 'Exception' with message 'DateTimeZone::__construct(): Unknown or bad timezone

new \DateTimeZone("UTC") - working

Hope it helps.

The issue should be already fixed.

I am getting this issue in magento 2.1.1. I can see this when I go to index page or when I try to checkout. The checkout doesn't complete showing error as

Call to a member function format() on null in /var/www/html/magento/vendor/magento/framework/Stdlib/DateTime/Timezone.php on line 284, referer: http://mysite/checkout/

would like to know how can I fix this or debug this?

Thanks,
Sadashiv

IntlDateFormatter may returns null instead of throwing an exception, see bug #66323

Usually, something like this is done:

$intlDateFormatter = new \IntlDateFormatter( ... );

if (!$intlDateFormatter) {
    throw new \RuntimeException(intl_get_error_message(), intl_get_error_code());
}

There is a known PHP issue with versions:
5.5.10–5.5.16
5.6.0

Update PHP version and it will be fixed.
