[tz] Please add Antarctica/Concordia and MZS to the timezone database

Dear timezone database maintainers, in 2011 you received a request from Paolo Perfetti to add two research stations located in Antarctica to the timezone database, Concordia: https://en.wikipedia.org/wiki/Concordia_Station that follows the Australia/Perth timezone, and Mario Zucchelli, https://en.wikipedia.org/wiki/Mario_Zucchelli_Station that follows New Zealand's NZST. Here is the original request: http://lists.debian.org/debian-glibc/2011/05/msg00157.html As I'm currently located in Concordia (and I will be for a year) I strongly second Paolo's request. As there are already other stations in the database I think that it shouldn't be problem to add these two. Thank you and greetings from Antarctica! Paride
