The government supports this new definition in many ways: by funding a primary frequency reference which feeds into UTC, the MSF broadcasts, the Greenwich atomic-clock powered NTP servers, the BBC pips.
I'd imagine there's been court cases that have decided this as well.
Does anybody have legal connections in the UK that could find out
(googling for this turns up nothing interesting).
For years, the official time in the US was UTC, even though the law said
mean solar time. The key was that the law actually said 'mean solar
time, as interpreted by the Secretary of Commerce' which chose to
interpret UTC as a mean solar time, since the averaging period wasn't
specified in the law.
