I note that the data for Africa/Timbuktu remains changed, and is not mentioned in NEWS.
Thanks, fixed with the attached patch.
- Africa/Accra gains DST between 1920 and 1935
Based on your explanation, this looks like a good change with a good justification. Can any more detail be added to NEWS?
NEWS contains one line about this, which should be enough for a heads-up. Details can be found in the comments in 'africa'.
your explanation does not indicate that replacement is right
Of course it's not 100% right. We don't have reliable information about old timestamps in Ghana. It would be better if we didn't have to put this low-quality data into the tz database at all. The only reason it's there is that the format requires it. Much of the pre-1970 data falls into this category, unfortunately. When the quality is this bad, there's nothing wrong with improving the quality even if the result is not perfect, or with removing bad data if this can be done without significantly affecting end-user applications.
