Clock module broken with libc++ 19

[vimproved]

I recently rebuilt my system after the libc++ 19 upgrade, and now Waybar's clock module is not showing any output. I've tested this with 0.10.4, 0.11.0, and lastest master. When run, Waybar repeatedly shows this error in the logs: [2024-09-28 09:51:34.001] [error] clock: ios_base::clear: unspecified iostream_category error

Note: This system also uses musl at its primarily libc, however I do not think this is related.

Here is some system info:

emerge --info gui-apps/waybar
