[hackers] [PATCH v2] Add clock icons to datetime module(v2)

From: mtdxwb <zdx1314520666_AT_163.com>
Date: Tue, 3 Mar 2026 22:17:51 +0800

This patch adds Nerd Font clock icons that change according to the
current hour (12-hour format). The icons are chosen based on the
hour string extracted via strftime(%I).

Changes:
- Moved variable declaration to function top
