Title: [Solved] How can I set the correct time zone on pi5?
Post by: Rabie on September 30, 2025, 05:35:39 AM

I added the following server to the file /etc/sysconfig/ntpserver:

Quote

cat /etc/sysconfig/ntpserver
0.de.pool.ntp.org

Then I run:

Quote

bash /etc/init.d/settime.sh

However, the time is still 2 hours behind.

date
Tue Sep 30 09:29:24 UTC 2025

When I run export TZ='Europe/Berlin', the time zone changes to Europe/Berlin, but the time is still 2 hours behind:

Quote

date
Tue Sep 30 09:31:38 Europe 2025

Can anyone help me?

I have "tz=utc-2" in cmdline.txt and the correct time is shown after starting wifi and "sudo getTime.sh".

it Worked thank you!  :)

I have another question:

How can I prevent the boot menu from showing up on the Raspberry Pi 5? (Please see the attached image.)

Also, how can I configure the Pi to always automatically boot from the SD card?

On other operating systems, I would normally use raspi-config, but I couldn’t find it on PiCore.

I think when setting the tz with continent/country/city like Europe/Stockholm, timezone have to lookup that in a file, so when I set the tz in tinycore I allways set to tz=CET-1CEST,M3.5.0,M10.5.0/3.

I think it's busybox for setting the correct tz, so you get correct time/date.

tz=CET-1CEST,M3.5.0,M10.5.0/3 kmap=qwerty/sv-latin1 host=raspxe noautologin nodhcp
