This may be a misunderstanding on my part about the file formats of zone.tab and zone1970.tab and how consistent they are expected to be.

I expect the exact zone IDs to be different, but there are only a few cases where countries differ in the number of referenced zone IDs.

I realize that zone.tab is intended for backward compatibility but it looks like it is being well maintained.

Is this difference expected? If it is, can somebody explain?

Details below the line.

Thanks for all the hard work.

Neil.
