I realise I am surfing the rim here, but...

system service hwclock allows changes to or from system time.

Set the Hardware Clock to the current System Time.
# hwclock --systohc

Set the System Time from the Hardware Clock.
# hwclock --hctosys

# hwclock --set --date="8:20:05"

But, generally I set the bios to UTC and the system takes care of the rest.

All the best.

however, it seem that there is not option to correct it in the setting

see my thread https://dev1galaxy.org/viewtopic.php?id=7636

consider if you want every device in your intranet to blast its IPv6 address all over the internet.
consider economy of data and privacy .

Change it to local in /etc/adjtime to give you what you want.

Sure, rolfie is right.
The computer's HW clock should be set to UTC. And the timezone (TZ) should be selected as to the standards.
When DST patterns change for some time-zones, the corresponding patches will be distributed. Another reason to update regularly.

I fear it doesn't work that way, never did.

Best for a Linux system: set the HW clock in the Bios to UTC. Set the time zone to your region.

Then install the packages ntpsec and ntpsec-ntpdate.

Last but not least: define a time server in /etc/ntpsec/ntp.conf. Works for me.

Note: when you dual boot with Windows, you have to change the registry to also set Windows to UTC.

sudo dpkg-reconfigure tzdata
[sudo] password for rich: 

Current default time zone: 'Europe/Rome'
Local time is now:      Tue Dec  9 17:16:46 CET 2025.
Universal Time is now:  Tue Dec  9 16:16:46 UTC 2025.

but the time is still ¹ hour behind.

Typing which ntp and pressing tab twice will get you a list of programs in your path with names starting with ntp. man ntp and tab twice will get a similar list of man pages. This trick is worth remembering next time you are not sure what a program should be called.

ntp and ntpdate are outdated since Daedalus. Look for ntpsec, e.g.

apt list ntpsec*

And to set ntp right, as you seem to refer to:
it's ntpsec to be installed.
And to check if it works:

ntpq -p

And in devuan 7 ??? These programs are present in Devuan 6 (Excalibur)
ntpdate was for older ditributions, like RedHat etc.

How set time to local-time in terminal?

dummy@example.com (kapqa) — Tue, 09 Dec 2025 16:00:30 +0000

Hello ,

i have set-up a Devuan 6 system with MATE Desktop;

now found out that the time is "1-hour-behind" due to computer probably aligned with greenwhich time or so.

now what i did previously was variously type in terminal like

"sudo ntpdate" or "sudo ntp" and the time would somehow set itself up to local-time.

now , however, both of tthese packages seem not present with devuan 7.

could you please show the proper method on aligning the time to local-time?

have already set the time in mate-desktop to local-location, but it seem not make-a-difference.

thank you very much.
