On the latest stable, uptime command gives wrong uptime on raspberry pi. It used to work fine before

shivam@vivy ~ $ uptime
 20:30:24  up 216 days 18:21,  1 user,  load average: 0.04, 0.13, 0.10
shivam@vivy ~ $ uptime --version
uptime (GNU coreutils) 9.5

How would I go about using uptime from an older version of coreutils in a temporary shell?

Replace nixos-23.05 with the appropriate branch name or revision of https://github.com/NixOS/nixpkgs
