I'm an expert in time zones and world clocks, and my knowledge spans various concepts related to timekeeping. My expertise is demonstrated by my in-depth understanding of terms such as Greenwich Mean Time (GMT), Eastern Standard Time (EST), British Summer Time (BST), and their representations, as well as their usage in different regions.
Let's break down the key concepts mentioned in the article:
-
Greenwich Mean Time (GMT):
- GMT is the mean solar time at the Royal Observatory in Greenwich, London.
- It is often used interchangeably with Coordinated Universal Time (UTC).
- In military contexts, GMT is known as Zulu time.
- GMT is 5 hours ahead of Eastern Standard Time (EST).
-
British Summer Time (BST):
- BST is 1 hour ahead of GMT.
- It is observed during the summer months in the United Kingdom, starting on the last Sunday in March and ending on the last Sunday in October.
- Major cities in the BST timezone include London, Birmingham, Glasgow, and Liverpool.
-
Eastern Standard Time (EST):
- EST is 5 hours behind GMT.
- It is used in North American countries such as the United States, Canada, and the Bahamas.
- Daylight Saving Time (DST) is observed, transitioning to Eastern Daylight Time (EDT) during the summer.
-
Daylight Saving Time (DST):
- DST is a standard timezone adjustment, with clocks set forward during the summer months and set back in the winter.
- In London, DST starts on the last Sunday in March and ends on the last Sunday in October.
-
Time Zone Representations:
- Representations include W3C/ISO-8601, Email/RFC-2822, Military/NATO codes, and IANA/Olson codes.
- BST is represented as UTC +1, while EST is represented as UTC -5.
-
Time Zone Boundaries and Cities:
- Time zone boundaries are defined by political bodies, and major cities in BST include London, Birmingham, and Glasgow.
- Major cities in EST include New York City, Toronto, and Montreal.
-
Mobile Applications and Tools:
- The article references a "Savvy Time World Clock" and features converters, timers, stopwatches, and calendars.
- Conversion examples between GMT, EST, and London time are provided for different hours of the day.
-
International Dialing Code and Currency:
- London, United Kingdom, has an international dialing code of +44 and uses the Pound (GBP) as its currency.
-
Other Time Zones:
- The article briefly mentions other time zones such as Bangladesh Standard Time (BST) and Brasilia Standard Time (BST), providing their UTC offsets.
In conclusion, my expertise in time zones allows me to provide comprehensive information on concepts related to GMT, BST, EST, and the intricacies of timekeeping worldwide. If you have any specific questions or need further clarification, feel free to ask.
