UTC Offset: UTC +5

Vostok Time (VOST) operates at UTC+5 year-round and is used at Russia's Vostok Station in Antarctica. VOST does not observe daylight saving time and is sometimes referred to as "Vostok Station Time." It provides a stable and practical time reference to manage daily operations, research projects, and logistics in the extreme Antarctic environment.

Importance and Global Use of VOST

Vostok Time (VOST) is crucial for coordinating scientific work, technical maintenance, and staff schedules at Vostok Station, which is known for its deep ice core drilling and climate research. A consistent time zone helps maintain safety, communication, and efficiency for researchers working under severe weather and extreme daylight conditions.

Globally, VOST supports collaboration between Russian and international scientists working in Antarctica under the Antarctic Treaty. Its stable UTC+5 offset facilitates the exchange of data, supports joint environmental monitoring, and helps align supply operations and research activities with other stations in the region.
