Hi,

I'm using SDK-LINUX-AM57X 06_03_00_106 on our custom board.

I want to change timezone UTC to JST(Tokyo/Asia).

Please give me any advice.

Regards,

Hi Toshio-san,

https://linuxize.com/post/how-to-set-or-change-timezone-in-linux/

I believe this is what you were looking for.

sudo timedatectl set-timezone Asia/Tokyo

root@j7200-evm:~# timedatectl
Local time: Tue 2022-02-08 22:48:55 JST
Universal time: Tue 2022-02-08 13:48:55 UTC
RTC time: n/a
Time zone: Asia/Tokyo (JST, +0900)
System clock synchronized: no
NTP service: active
RTC in local TZ: no

Hi Keerthy,

Thanks for your reply.

I executed on our board.

====

root@am57xx-evm:~# timedatectl set-timezone Asia/Tokyo
Failed to set time zone: Invalid time zone 'Asia/Tokyo'

====

The Linux SDK do not have tzdata package.

I checked

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/811205/linux-am5728-timezone-change.

This issue is over 3 years ago.

Is tzdata_2018f-r0_all.ipk the newest?

Hi Toshio-san,

Okay. I am seeing the issue on AM573x IDK as well. The 6.03 version does not seem to have the timezone package.

Hi Toshio-san,

tzdata package is available as part of the oe-core layer it is present in "./oe-core/meta/recipes-extended/timezone/tzdata.bb"

This is an open source package and customers who need this package can compile this using bitbake and install them into their filesytem.

I quickly checked whether this is buildable easily and it is very simple to build. On the AM57 SDK, use this command.

TOOLCHAIN_BASE=/sdk/tools MACHINE=am57xx-evm bitbake -k tzdata

I recommend the customer to build and use the tzdata package.

Regards

Karthik
