[hackers] [slstatus][PATCH] Add clock icons to datetime module

From: mtdxwb <zdx1314520666_AT_163.com>
Date: Sat, 28 Mar 2026 15:43:17 +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:
- Removed unused hours variable
- Removed useless strftime call
