Understanding Time Zone Terminology

UTC (Coordinated Universal Time)

The primary time standard by which the world regulates clocks. It's the successor to GMT (Greenwich Mean Time) and serves as the basis for time zones worldwide.

IANA Time Zone Database

The official database of time zones maintained by the Internet Assigned Numbers Authority. Our tool uses the standard IANA timezone codes like "America/New_York" and "Europe/London".

Daylight Saving Time (DST)

The practice of setting clocks forward one hour during summer months to extend evening daylight. Our tool automatically handles DST transitions for all supported time zones.

Offset vs. Time Zone

Offset: The difference in hours from UTC (e.g., UTC+5, UTC-8)
Time Zone: A region where the same standard time is used (e.g., Eastern Time, Pacific Time)

Troubleshooting Common Issues

Time Showing as "Invalid Timezone"

Problem: Some timezones display "Invalid timezone" instead of the time.

Solution: This usually indicates an issue with the specific timezone data. Try refreshing the page or selecting a different timezone. The issue typically resolves itself.

Favorites Not Saving

Problem: Your favorite timezones disappear after closing the browser.

Solution: Favorites are saved locally in your browser. If they're not persisting, check if you're using incognito/private browsing mode or if your browser is clearing local storage.

Search Not Finding Timezones

Problem: Can't find a specific timezone in the search results.

Solution: Try searching with different terms. You can search by city name, country name, or the IANA timezone code. If a location still doesn't appear, it might not be in the standard timezone database.

Time Not Updating

Problem: The time display isn't updating automatically.

Solution: The tool updates every second automatically. If it's not updating, try refreshing the page. Some browser extensions or strict privacy settings might interfere with the automatic updates.

Best Practices for Time Zone Management

For Business Use

• Document your team's time zones - Keep a shared list of team member locations
• Use consistent naming - Name favorites clearly (e.g., "SF Office" vs "San Francisco")

For Personal Use

• Create travel presets - Save favorite combinations for frequent trips
