svelte-time: SvelteKit build fails on dayjs ES module import not supported

Hi,

Thanks for this cool lib/component. It works great in dev mode for a Sveltekit project I am developping, but when running npm run build it fails with the following error :

Error [ERR_UNSUPPORTED_DIR_IMPORT]: Directory import '/home/.../node_modules/dayjs/esm' is not supported resolving ES modules imported from /home/.../.svelte-kit/output/server/chunks/index-5e596d58.js
Did you mean to import dayjs/esm/index.js?

Any idea how this could be fixed? 🙏
