Inaccurate Airport Data

[Unknown98]

It's +13. I fixed it now.

For the timezone offset, always use the map that is linked on the add airport page: https://upload.wikimedia.org/wikipedia/c..._Zones.png

That will give you the correct offset. The other website should only be used to determine if the airport uses DST or not. Because timezone offset will be different depending on DST. So we just use the UTC offset, which never changes. That's what the map displays.
