treewide: avoid strftime %k for portability

The musl strftime(3) implementation on AlpineLinux 3.19.0
doesn't support `%k' and `%k' isn't in POSIX, either.  So we
fall back to using the `sprintf' perlop in the user-facing UI
since leading zeroes require needless overhead for my eyes and
brain to parse in the time.
