How World Clock Works

Time Zones Explained

World clocks display the current time across different time zones. The Earth is divided into 24 main time zones, each roughly 15 degrees of longitude apart. As the Earth rotates, different parts of the world experience daylight at different times.

Accurate Time Synchronization

Our world clock system synchronizes with atomic clock servers using Network Time Protocol (NTP) to maintain accuracy within milliseconds. This ensures you always see the precise current time for any location.

Daylight Saving Time

The clock automatically adjusts for Daylight Saving Time (DST) changes in applicable regions. DST dates vary by country and region, but our system keeps track of these changes to display the correct time year-round.

Features

  • Real-time updates across all time zones
  • Automatic DST adjustments
  • Support for major cities worldwide
  • Toggle between analog and digital display
  • Customizable timezone selection
