Does the gap change during the year?

Yes, because of daylight saving. Until 28 Mar 2027: HST is 11 h behind CET. From 28 Mar 2027 to 31 Oct 2027: HST is 12 h behind CET. From 31 Oct 2027 to 26 Mar 2028: HST is 11 h behind CET.

CET next changes its clocks on 28 Mar 2027 (forward 1 h, to UTC+2), then on 31 Oct 2027 (back 1 h, to UTC+1). HST does not change its clocks.
