COMMON QUESTIONS
Frequently Asked Questions
Timezone indices, daylight savings & local offsets decoded? How does the world clock tool work?
It reads browser system dates, applies chosen IANA timezone keys, and formats localized times client-side.
? Are my planned meeting times or selected cities sent to databases?
No. All timezone offsets, city lists, search queries, and sliders run locally.
? How does the tool handle daylight saving differences?
The JS time compiler automatically checks IANA transition records to apply active DST shifts.
? Can I display times in a 24-hour military layout?
Yes, you can toggle between standard 12-hour AM/PM and 24-hour display formats.
? Does it support half-hour and quarter-hour timezone offsets?
Yes. It correctly parses regional non-standard offsets (like India's UTC+5:30 or Nepal's UTC+5:45).
? Will the clocks lag if I keep the page open?
No. Clock renders are optimized using high-efficiency requestAnimationFrame intervals to tick in perfect sync.
