Time in Antarctica: No Single Time Zone

Antarctica spans all lines of longitude, so it has no official time zone. Research stations adopt practical conventions:

• McMurdo Station (US) & Scott Base (NZ): New Zealand Standard Time (UTC+12/13).
• Rothera & Halley (UK): British Standard Time (UTC+0/1).
• Others: Some use UTC; others follow their home country's time or the supply route's time zone.

There is no "Antarctica time" applicable continent-wide.
