6. Frequently Asked Questions (FAQ)
6.1 How does daylight saving time (DST) affect time zone conversions?
Daylight saving time shifts local clocks forward or backward by typically one hour during spring and autumn. This tool automatically accounts for regional DST transitions using standard IANA timezone database definitions, ensuring that displayed offsets and converted hours remain accurate throughout seasonal shifts.
6.2 What is the difference between UTC and GMT?
Coordinated Universal Time (UTC) is the primary atomic time standard used across the globe for synchronization, while Greenwich Mean Time (GMT) is a timezone representing solar time at the Royal Observatory in Greenwich, London. In practice for scheduling and offsets, both share the same base reference (UTC+0).
6.3 Can I compare overlapping working hours across multiple continents?
Yes. The interactive timeline slider highlights business hours across all selected locations simultaneously. You can visually identify overlapping work windows between team members in the Americas, Europe, Asia, and Australasia.
6.4 Is any location or schedule data stored on external servers?
No. All timezone calculations and timeline adjustments occur strictly inside your browser session. ZenUtilify does not record, log, or transmit your added cities, meeting times, or personal schedule preferences.
