I should point out that UTC didn't begin until 1960...

The 28 minutes jump is likely Iceland coming into alignment with GMT, for much the same reasons as Ireland did; to improve trade and commerce in a world now using telegraphs, telephones and trains. We're ok becoming disconnected from mean solar time in order to connect more with each other.

Samoa skipped a day in 2011, jumping from UTC−11:00 to UTC+13:00, so that it could align with Australia and New Zealand, its biggest trading partners -- so Australia's Friday is also Samoa's Friday.

We'll always have discontinuities in civil timekeeping, as it's there to serve the whims of humans, not the other way around.

The UK skipped 11 days in 1752. There were riots.
