Some research stations and bases observe their own time zones, mainly those closest to other continents. For example:
- The New Zealand Antarctic Research Institute (Scott Base) and the United States McMurdo Station observe New Zealand Standard Time (NZST) +12:00 UTC
- The British Antarctic Survey stations (Rothera Research Station and Halley Research Station) observe British Standard Time (BST) +06:00 UTC
Others use the Universal Coordinated Time (UTC) or a time zone based on the geographic location.
