The differences between 2014e and 2014f-proposed can be seen here: https://github.com/jodastephen/tzdiff/commit/c812da9e12bd6f8aa52fa2dd758e236... I don't normally use a web-based interface, though; I use 'git' directly. For example, on my development host the shell command 'git diff 2014e' outputs a text file containing all the changes since 2014e.
The key reason for generating the tzdiff link is to be able to check what the *end result* of the changes is. ie. sometimes it is a lot easier to see the actual result of the changes when resolved into actual transitions.
- 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?
- Africa/Freetown loses its entire history of DST
Thank you for the explanation. This level of detail helps. However while this indicates that the current data is wrong, your explanation does not indicate that replacement is right. This is the nub of the problem. (Determining "right" is of cause hard if even possible for these locations). In this case your explanation goes just about far enough to say that removal is justified, but the single Linked 1912 is not explained. The same applies to the other conversion to links. In each case, the LMT changes and often the year that standard time starts is changed. I, and others, would strongly prefer the data to be left alone until research shows something clearly better. If filtering to reduce the size of the database is needed, then it should be done in code, not the in original source data. Stephen
