# About This Tool

A Time Zone Converter is a temporal utility that translates a specific clock time from one geographic region to another, accounting for both UTC (Coordinated Universal Time) offsets and local Daylight Saving Time (DST) regulations. It utilizes a comprehensive database of global city data to ensure that '9:00 AM' in San Francisco is correctly mapped to the current equivalent in Sydney, even during the weeks when different countries switch their clocks for the seasons.

# UTC vs. GMT: What's the difference?

People often use them interchangeably, but:

  • UTC (Coordinated Universal Time) is a Time Standard. It does not change with seasons.
  • GMT (Greenwich Mean Time) is a Time Zone used in the UK and Africa. It can switch to BST (British Summer Time) in summer.
  • Best Practice: Always schedule technical events or server logs in UTC to avoid confusion.
