Do Penguins Use Daylight Saving Time?

Do penguins adhere to daylight savings time?  Do penguins even care?  Antarctica where two major penguins species reside (Emperor and Adlie) sits on every line of longitude, due to the South Pole being situated near the middle of the continent. Theoretically Antarctica would be located in all time zones, however areas south of the Antarctic Circle experience extreme day-night cycles near the times of the June and December solstices, making it difficult to determine which time zone would be appropriate. For practical purposes time zones are usually based on territorial claims, however many stations use the time of the country they are owned by or the time zone of their supply base (e.g. McMurdo Station and Amundsen–Scott South Pole Station use New Zealand time due to their main supply base being Christchurch, New Zealand).Many areas have no time zone since nothing is decided and there are not even any temporary settlements that have any clocks. They are simply labeled with UTC time.  With almost six months of daylight and six months of darkness in most of Antarctica we must conclude that daylight savings time in the southern continent does not make any sense, so there’s no “fall back, spring ahead” in Antarctica, and since penguins can’t tell time, we must conclude the Antarctic time zone phenomenon moot. At least for penguins.
