Zfs list creation time in standard time not unix time

x86_64 machine (glibc):

zfs list -t snapshot -s creation -o name,creation

system/home@backup_2023-07-16-0659 Sun Jul 16 0:59 2023
system/root@backup_2023-07-16-0659 Sun Jul 16 0:59 2023
system/home@backup_2023-07-16-0706 Sun Jul 16 1:06 2023
system/root@backup_2023-07-16-0706 Sun Jul 16 1:06 2023

Raspberry Pi 4 (musl):

zfs list -t snapshot -s creation -o name,creation

server/root@base-2023-07-16-2234 1689546867
server/home@base-2023-07-16-2234 1689546868
server/home@update_2023-07-16-2320 1689549658
server/root@update_2023-07-16-2320 1689549658

Why is the Raspberry Pi printing the creation time in unix time?

I don’t have any idea what could be causing this. Please tell me how to print snapshot creation times in standard time, not unix time.

Thank you
