WorldClock Suite is a dual-modality, zero-dependency time
**WorldClock Suite** is a dual-modality, zero-dependency time-tracking application engineered entirely in pure ANSI C. It delivers two distinct execution paradigms: a lightweight, cross-platform CLI utility (`worldclock.c`) for terminal/SSH workflows, and a feature-rich native Windows GUI (`worldclock_gui.c`) built with Win32 API and GDI. Both binaries share a unified timezone database covering **200+ countries and regions**, providing real-time local time, UTC offsets, and Daylight Saving Time status. The console version features ANSI color-coded tabular rendering with dynamic time-of-day theming, while the GUI offers a flicker-free, double-buffered analog clock with interactive timezone selection, multi-panel layout, and custom typography. Designed for engineers, sysadmins, and global coordinators, the suite emphasizes strict memory safety (zero dynamic allocation), deterministic resource lifecycle management, and efficient rendering pipelines—requiring no external libraries beyond standard C and native OS APIs. With a compact binary footprint (~50 KB), sub-millisecond computation latency, and full compatibility from Windows XP to 11 (x86/x64) plus POSIX systems for CLI, WorldClock Suite exemplifies disciplined native C programming. Licensed under MIT, it offers complete transparency for educational use, customization, or integration into larger toolchains—delivering reliable, high-performance global time awareness with minimal system overhead. 🌍⏱️💻
