He said that some Antarctic locations set their local 268# time so that noon is the warmest part of the day, and that this 269# changes during the year and does not necessarily correspond to mean 270# solar noon. So the Vostok time might have been whatever the clocks 271# happened to be during their visit. So we still don't really know what time 272# it is at Vostok.
