: De jure it is "Greenwich mean time". AIUI when GMT was last maintained as a solar timescale it did not correspond exactly to modern UT1 nor UT2, though it was similar.
: How does UTC+DUT1 relate to UT1?
And the on-time marks for the signals are UTC, with a resolution of
microseconds. The resolution of the DUT1 data is only 100ms. This
sounds to me like the official time is UTC, and that, oh, by the way,
there's this extra parameter that kinda sorts relates to something
Also, this value is not disseminated by ntp or any other means that
reports the official time.
I'd have to say this argument is a stretch too. As Tony points out
"traditional" GMT isn't UT1 nor UT2...
