Description

My local time is 2:44 PM, but hyprlock shows 10:44 AM
Occurs with both $TIME12 and $TIME

My system was first on PDT, but then I set the time to ART (+4 hours) when I first got to Argentina (where I'm currently staying)

How to reproduce

Unsure, this may be a tzdata issue? (ref: Alexays/Waybar#3570)

we use the C++ stdlib here with std::chrono::current_zone so I am unsure how this could be a problem with hyprlock. @PaideiaDilemma any ideas?

[PaideiaDilemma]

I can also reproduce it when setting my tz to different time zones.
Fixable by either downgrading tzdata, or using gcc >= 14.3 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116657)

Since you closed the issue in waybar my guess is that waybar was compiled with a different stdlib that works with the new tzdata version and hyprlock wasn't.

It seems that GCC 14.3 isn't available on Arch Linux -- this should've already been fixed in libstdc++, but for some reason, building hyprlock from source doesn't fix the issue (even though it does for waybar) 🤔

(and for anyone reading this affected, text = cmd[update:1000] echo "$(date +'%l:%M %p')" works as an alternative)

I think hyprlock is build with gcc and waybar with clang?
Also on archlinux the waybar PKGBUILD depends on 'libdate-tz.so', but hyprlock doesn't.

That'd explain it
