The continent spans all longitudes. Research stations adopt the time zone of their **supply country** or **logistical convenience**, creating a patchwork:
| Station / Territory | Operator | Time Zone (Standard) | vs. UK (GMT/UTC) |
|---|---|---|---|
| Rothera (British Antarctic Territory) | UK | UTC−3 | 3 hrs behind |
| Mawson (Australian Antarctic Territory) | Australia | UTC+6 | 11 hrs ahead |
| McMurdo (US Antarctic Program) | USA | UTC−12 / UTC+12* | 13 hrs behind / 12 hrs ahead* |
| Novolazarevskaya (Russian) | Russia | UTC+3 | 6 hrs ahead |
| Carlini Base (Argentine) | Argentina | UTC−3 | 3 hrs behind |
*McMurdo often uses NZ time (UTC+12/13) for logistics with Christchurch.
Some stations shift to match home-country daylight saving or operational schedules.
Bottom line: Specify the station—there is no "Antarctica time."
