Barbados
The attached patch 0002 applies these changes for Barbados. I noticed that the 1944 DST regulation, unlike the 1942 and 1943 regulations, only advanced clocks by half an hour, so I incorporated that change.
Gambia
Malawi
Sierra Leone
The attached patch 0003 handles these three entries, which are all in our 'backzone' file. For Sierra Leone specifically, I took a slightly different approach in modeling the 1939-09-05 transition as a switch to year-round standard time of -01 for the ~2 years it was observed. I've also retained the 1957–1962 DST transitions from Shanks for the time being, in the absence of better data or particularly strong evidence that they should be discarded entirely. I've installed both of these patches in the development repository. Since we already incorporated the information you sent on Nigeria earlier as part of the work on (2), I believe this completes the work raised in this (3) thread. -- Tim Parenti
