GMT/Zulu Time representation in iPhone's world clock

I would like to understand why GMT or Greenwich Mean Time aka Zulu Time is not represented in the world clock for iPhone. I understand that London is there, however it is not referred as London Mean Time (LMT). In virtually any medium, that time zone is referred as GMT or Zulu Time. I feel that for factual consistency, the clock app on iPhone should replace “London, England” with “Greenwich, England” altogether or at least include GMT, even though both represent the same time zone.
