Sorry I am also new to this and am trying to understand how the rule below is applied: # Ghana # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Ghana 1936 1942 - Sep 1 0:00 0:20 GHST Rule Ghana 1936 1942 - Dec 31 0:00 0 GMT
I read it as "Ghana" rules were only in effect from 1936 to 1942.
This is a common confusion. The Rule statements generate transitions; in this case, every year between 1936 and 1942, two transitions are generated, one from GMT to GHST (save 20 minutes), and one from GHST to GMT. Since no transitions happen after December 31, 1942, Ghana remains on GMT. -GAWollman
