Interactive world clock

A live world clock with a 12H/24H tab toggle, a focus card that ticks in real time, and four city cards showing local time, UTC offset, and day or night state. A scrolling marquee at the bottom loops the time zone names for extra motion. Use it on global team pages, travel and events sites, financial market overviews, or newsroom homepages where "what time is it right now, everywhere" matters.
