Scheduling a episode gives an error

[superhua]

I get this error when trying to a schedule a podcast episode (I deleted my city):

DateInvalidTimeZoneException
DateTimeZone::__construct(): Unknown or bad timezone (America/CityDeleted)
at /app/code/vendor/codeigniter4/framework/system/I18n/TimeTrait.php:92

When I copy the stack trace:

DateInvalidTimeZoneException: DateTimeZone::__construct(): Unknown or bad timezone (America/CityDeleted) in /app/code/vendor/codeigniter4/framework/system/I18n/TimeTrait.php:92
Stack trace:

#9 /app/code/public/index.php(61): CodeIgniter\Boot::bootWeb()

This happens both on the Cloudron demo server and my server.

Is this an upstream issue?

I did a comparison what timezone on Linux exist for America and compared them to the list of supported timezones in https://www.php.net/manual/en/timezones.america.php

Comparison can be found here: https://regex101.com/r/mXRK1J/1
Not supported timezones are:

[...]
America/Ensenada
America/Fort_Wayne
[...]

Setting my timezone to America/Fort_Wayne:

timedatectl
Local time: Mi 2025-05-28 02:04:21 EDT
Universal time: Mi 2025-05-28 06:04:21 UTC
RTC time: Mi 2025-05-28 06:04:20
Time zone: America/Fort_Wayne (EDT, -0400)
System clock synchronized: no
NTP service: inactive
RTC in local TZ: no

In a Chrome based Browser running:

console.log(Intl.DateTimeFormat().resolvedOptions().timeZone);
America/Indianapolis

Good America/Indianapolis is not on the list https://www.php.net/manual/en/timezones.america.php

DateInvalidTimeZoneException: DateTimeZone::__construct(): Unknown or bad timezone (America/Indianapolis) in /app/code/vendor/codeigniter4/framework/system/I18n/TimeTrait.php:92

#9 /app/code/public/index.php(61): CodeIgniter\Boot::bootWeb()
#10 {main}

This is the exact error you are having.

Now in FireFox running:

console.log(Intl.DateTimeFormat().resolvedOptions().timeZone);
America/Indiana/Indianapolis

America/Indiana/Indianapolis is on the list of supported timezone https://www.php.net/manual/en/timezones.america.php

And the scedule publish of castopod worked fine.

Solution / Error explanation

It seems your are using a Chrome based Browser on a Unix based system (macOS / Linux) and a Timezone that gets converted into a TimeZone that is not support by PHP.

Quick Fix

Use a different timezone that is more generic and check in the web console with:

console.log(Intl.DateTimeFormat().resolvedOptions().timeZone);

if the timezone returned is avaiable in https://www.php.net/manual/en/timezones.america.php

What should be done in a perfect world

An issue should be raised with PHP and the Chomerium based browser you are using about this specific issue and Timezone.
Either PHP should support all timezone or the chrome based browser should convert it into a supported PHP version one like FireFox does.

I hope this will solve your issue.

Hello @superhua
This php error is saying that the timezone you have used is not supported and thus throwing this error.

Error: https://www.php.net/manual/en/class.dateinvalidtimezoneexception.php
Thrown when an incorrect value is passed to DateTimeZone::__construct().
=> https://www.php.net/manual/en/datetimezone.construct.php

From the parameter timezone:

One of the supported timezone names, an offset value (+0200), or a timezone abbreviation (BST).

https://www.php.net/manual/en/timezones.php

Please check if your city is even in the support timezone names and report back.

If this is truly the error, this might be something for upstream for better error handling in the UI to inform the User that the given timezone is not supported.

Not seen an issue about this in the official issue tracker for castopod https://code.castopod.org/adaures/castopod/-/issues/

[superhua]

Thank you.

My city is in the support timezone.

Further, I don't see a place to specify a timezone. That is, I think Castopod is automatically assigning the timezone.

[james]

Hello @superhua
I will look into it.

[james]

After looking into the code of castopod I can see that the timezone is taken from the browser directly. There is no place to configure this, only on the local system level.

Some testing:
Windows 11, setting the Timezone to (UTC-04:00) Georgetown, La Paz, Manaus, San Juan since this timezone also includes a _ character for extra measure.
In a Chrome based browser I validated the timezone in the console and tried to schedule publish a podcast.

console.log(Intl.DateTimeFormat().resolvedOptions().timeZone);
America/La_Paz

This seems to be working.

Thank you for your in-depth research and description!

Hello @superhua

Happy to help. Is this now solved from your point of view?

[superhua]

Yes; thank you.
