@taylorotwell i am getting this error, please rectify.

[overtrue]

config/app.php:

'timezone' => 'UTC',

[frankiecmk]

'timezone' => env('APP_TIMEZONE'),

@overtrue i did set in config/app.php and .env file APP_TIMEZONE=Asia/Kuala_Lumpur

[overtrue]

dd(env('APP_TIMEZONE')) ?

[frankiecmk]

@overtrue it shows Asia/Kuala_Lumpur, the error is only happen when there is a huge spike on traffic.

[overtrue]

try add a default value:

'timezone' => env('APP_TIMEZONE', 'Asia/Kuala_Lumpur'),

[phanan]

This is often seen when you have subdir(s) with the same file names under config dir, since Laravel 5 dropped cascading support. I thought this has been fixed since 5.0.3 though.

[frankiecmk]

@overtrue it works fine, but without the default value will prompt error if there is huge spike of traffic.

[frankiecmk]

@phanan: there is no same file names under config dir.

[phanan]

Hmm... Try logging config('app') under huge spike of traffic and see what's there, then? If it's empty, maybe your app has some problem loading the config files under such circumtances.

[crynobone]

Probably need more detail, version used, opcache (could cause issue) or even might be related to #7354

[frankiecmk]

@crynobone Yes, this is related to #7354 due to PHP thread-safe i guess.

[crynobone]

There isn't any workable solution right now, #7425 was merged but later reverted due to regression bug 866a8cf#commitcomment-9767647

[jebog]

Please check your php.ini date.timezone directive

[masonfox]

I'm getting this on a windows machine:

date_default_timezone_set(): Timezone ID 'Enter the new date: (mm-dd-yy)' is invalid

config/app.php = 'timezone' => 'UTC',

[ghost]

date_default_timezone_set('UTC')

[stadeli]

How do we know which one of the 20 suggested answers is the correct one???

[mashum]

By using function timezone_identifiers_list(); will confirm the timezone supported in php use this if(!in_array('your timezone', $zoneList)) { set default timezone here }

[judegoz]

config/app.php:

'timezone' => 'UTC',

i did same but still fatal error
