What day is it right now? :-)
From what I can find, TAI is defined as "seconds since the TAI epoch", which, if this page
http://www.hko.gov.hk/gts/time/basicterms-TAI.htm
is correct, is "1958 January 1 d 0 h 0 min 0 s"; if so, presumably that's "1958 January 1 d 0 h 0 min 0 s GMT".
Not quite. TAI is a clock, with hours, minutes, and seconds. It was synchronised with GMT (UT1, actually) at the start of 1958.
I suspect that means that the answer to "what day is it right now" could differ between the UTC and TAI zones near the insertion of a leap second.
It differs anyway. At present TAI moves to a new day 34 seconds before UTC does.
Then again, it could differ between different locations on the earth....
TAI and UTC aren't time-zone dependent. -- Clive D.W. Feather | If you lie to the compiler, Email: clive@davros.org | it will get its revenge. Web: http://www.davros.org | - Henry Spencer Mobile: +44 7973 377646
