How to set the correct time zone in `configuration.nix`

FrancoBujakiewicz · July 13, 2025, 11:36am

My laptop time is 3 hours advanced, for Hardware/BIOS issues I thought. How I can set the correctly hour in configuration.nix? I’m from Argentina I set it as time.timeZone="America/Argentina" but it still advanced 3 hours.

Linux usually assumes that the BIOS/hardware clock is in UTC, if it isn’t, this explains any difference between your wall clock and the clock displayed by your computer.

If there is also a Windows installed that you Dualboot, then things become more complicated, as windows by default assumes that the hardware clock is “local”.

In that case you have 2 possible solutions:

Tell windows to use hardware as UTC (error prone and buggy)
Tell Linux to use hardware clock as local (I don’t remember what option does this)

FrancoBujakiewicz · July 13, 2025, 11:49am

I’m not have a dualboot, just NixOS installed. There is 8:46 AM actually, In my laptop is 11:46, exactly minutes, just 3 hours advanced. That hours problem isn’t new, In Windows with dualboot was usually happened. If I set the time manually, after reboot its adds 3 hours. I just need to know how to set it, sync with a UTC server, maybe?

NobbZ · July 13, 2025, 12:54pm

Time sync should be active by default, though might be ineffective due to skewed base time.

Please make sure your hardware clock is set to UTC. You do that in your firmware settings.

FrancoBujakiewicz · July 13, 2025, 1:25pm

Yeah. I can set it manually in BIOS. Could ends good here but the Authentication browser extension for two-factor doesn’t work now, and the ntp sync overrides the time. Now I need my time and that the extension works.

Could it maybe be that your timezone is set to something else in your desktop environment? Does date have the correct time? If totp 2fa isn’t working that’s an indicator that your computer has the wrong UTC time. You may want to check your hardware configuration. You don’t have time.hardwareClockInLocalTime = true; set anywhere, do you?

FrancoBujakiewicz · July 13, 2025, 3:28pm

I’m just using Xmonad window manager, date doesn’t show the correct time, neither set hardware clock option in configuration.nix, in hardware-configuration.nix I don’t have nothing about time, just de default time.

ttamttam1 · July 13, 2025, 3:40pm

This is really strange. It should “just work”. I would expect your hardware clock to be in UTC and then timezone in ‘America/Argentina’. And then if both of those were true I’d expect date to give the correct time in ART, or at least the correct time in UTC. If there’s no dualbooting I wouldn’t expect it to still be off. Maybe your ntpd logs will have a hint?

FrancoBujakiewicz · July 13, 2025, 4:23pm

In my firmware interface I exclusively change the time itself, no other time options.

What’s the output of timedatectl?

FrancoBujakiewicz · July 13, 2025, 7:23pm

Has the wrong time

 Local time: Sun 2025-07-13 19:22:48 UTC
           Universal time: Sun 2025-07-13 19:22:48 UTC
                 RTC time: Sun 2025-07-13 19:22:48

System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

ttamttam1 · July 13, 2025, 9:38pm

So your local time is the same as UTC, but your system time (which is assumed to be UTC) you’ve set to local time while debugging this. So now your whole system thinks it’s running UTC but also that it’s 3 hours in the past, this is why NTP is getting a desync error and TOTP is failing (and probably other crypto related issues).

I would start by setting your bios clock back to UTC (3 hours ahead). Then make sure NTPd synchronizes correctly in the logs. Once that happens, and you’re back to UTC (3 hours ahead), I would take another look at your timezone configuration. From what I can tell, America/Argentina is not a valid IANA time timezone. Try setting it to one of:

America/Argentina/Catamarca
America/Argentina/Cordoba
America/Argentina/Jujuy
America/Argentina/Lo_Rioja
America/Argentina/Mendoza
America/Argentina/Rio_Gallegos
America/Argentina/Salta
America/Argentina/San_Juan
America/Argentina/San_Luis
America/Argentina/Tucuman
America/Argentina/Ushuaia

Whichever is closest to you.

ttamttam1 · July 13, 2025, 9:42pm

For reference, my closest timezone is America/New_York and my timedatectl looks like this:

➜ timedatectl 
               Local time: Sun 2025-07-13 17:39:15 EDT
           Universal time: Sun 2025-07-13 21:39:15 UTC
                 RTC time: Sun 2025-07-13 21:39:15
                Time zone: America/New_York (EDT, -0400)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

The fact that your timzone is n/a led me to lookup the IANA timezones and find that America/Argentina is not listed. You really think it would be… but I guess not.

waffle8946 · July 13, 2025, 11:55pm

I’m a little confused, their time seems correct for UTC.
Not sure why their ntp service is choking.

Side note: why ntpd and not systemd-timesyncd?

FrancoBujakiewicz · July 14, 2025, 12:25am

The problem was it, I set it as America/Argentina/Cordoba and is ok now

Thank you guys!

ttamttam1 · July 14, 2025, 12:30am

You’re right the UTC time looked correct. I thought it might have been wrong because it sounded like from the conversation that it was manually set to local time at some point, but I was wrong. As for ntpd, also my bad, I forgot timescyncd was the default because I was using ntpd on my personal config.
