@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.

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 https://github.com/laravel/framework/commit/866a8cfc58430830069bd24feacf2d81e99385a2#commitcomment-9767647

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 }
