What's an International tike zone. and how is it different from a local time zone?

Or are you referring to GMT?

Local time zones are relative to the prime meridian, an imaginary line which circles the earth, passing over both poles and a marker at the Greenwich Observatory near London England. Every 15 degree meridian west of the observatory marks a new time zone, 1 hour earlier than the observatory.

The International Tike Zone is a childrens play area at most major international airports.

While this tread is full of amusement, I suppose the OP wanted to see something like this:

If so, the GPX layer is available at Layers Library | Official OpenCPN Homepage

Hi,

the timezone display is not working for me, i can even find it in the layers screen and of course all other layers are OK.

I was so taken up with the comedy (?) part of my reply that I screwed up on the time zone boundarys; fortunately no one has corrected me yet.

The marker at the Greenwich Observatory actually lies in the center of their time zone. the zone goes from 7.30W to 7.30E. Each succeeding 15 degree wide belt is another time zone. Those are geographical time zones. However, countries which overlap time zones often declare the whole country, or significant parts of it, in their "main" time zone. Western Ireland, for instance, uses UTC although it actually is in the next western time zone, UTC-1.
