DateInvalidTimeZoneException: Unknown or Bad Timezone Error (Asia/Calcutta)

[Wilsong]

Hi,

I’m encountering an issue related to the timezone settings on my Nextcloud instance. Here are the details of the error:

DateInvalidTimeZoneException
DateTimeZone::__construct(): Unknown or bad timezone (Asia/Calcutta)
Error while running background job OCA\DAV\BackgroundJob\EventReminderJob (id: 12, arguments: null)

It seems like the timezone “Asia/Calcutta” is being flagged as unknown or incorrect. I’ve double-checked my configuration, and “Asia/Kolkata” is the correct and recognized timezone in PHP and most systems now, replacing “Asia/Calcutta.”

Could this be the source of the issue? If so, how can I update the timezone for my instance or background jobs to resolve this? Any guidance or suggestions would be appreciated.

Thanks in advance!

@Wilsong

how can I update the timezone for my instance

You could try adding the following line to the config.php, or change it accordingly if it’s already there:

'default_timezone' => 'Asia/Kolkata'

And you should probably also change it accordingly in the respective php.ini files on your system: PHP Modules & Configuration — Nextcloud latest Administration Manual latest documentation

Are you perhaps not running on an LTS release of Debian (or similar)?

I believe you can install the package tzdata-legacy or similar.

Hello Jtr
I wanted to share an update regarding the time zone issues we were facing. By running the command tzdata-legacy, the problem has been successfully fixed.

Thank you
