Common Time Zone Formats and Examples (timeZone)

timeZone is used with the Intl.DateTimeFormat API:

1. Common Time Zone Strings (IANA-TZ Format)

These strings are based on the IANA Time Zone Database, which defines time zones used worldwide:

Time Zone	Description
UTC	Coordinated Universal Time
America/New_York	Eastern Standard Time (EST)
Europe/Berlin	Central European Time (CET)
Asia/Tokyo	Japan Standard Time (JST)
Australia/Sydney	Australian Eastern Time (AET)
Africa/Cairo	East Africa Time (EAT)
Pacific/Auckland	New Zealand Standard Time (NZST)

2. Short Time Zone Formats (Offset-based)

These formats use the offset from UTC in hours and minutes. Examples:

Time Zone	Description
GMT	Greenwich Mean Time
+02:00	Two hours ahead of UTC
-05:00	Five hours behind UTC

3. Abbreviated Time Zone Codes

Note: These are not supported by the Intl API and are not standardized. However, many abbreviations are commonly used in practice, such as:

Abbreviation	Description
PST	Pacific Standard Time (UTC-8)
CET	Central European Time (UTC+1)
IST	Indian Standard Time (UTC+5:30)
