Does the gap change during the year?
Yes, because of daylight saving. Until 14 Mar 2027: CLT is 1 h ahead of AST. From 14 Mar 2027 to 4 Apr 2027: CLT is the same time as AST. From 4 Apr 2027 to 5 Sep 2027: CLT is 1 h behind AST. From 5 Sep 2027 to 7 Nov 2027: CLT is the same time as AST.
AST next changes its clocks on 14 Mar 2027 (forward 1 h, to UTC−3), then on 7 Nov 2027 (back 1 h, to UTC−4). CLT next changes its clocks on 3 Apr 2027 (back 1 h, to UTC−4), then on 5 Sep 2027 (forward 1 h, to UTC−3).
