Hello,
You should be aware that there is a _huge_ difference between UTC and TAI:
UUTC is a timescale which have as many realisations UTC(k) as there is
laboratories who want/need to realize it, but there is _no_ realtime
representation of TAI and the recommendation of BIPM/CCTF is that there
should _not_ be! It is a timerscale that is computed on a monthly basis (cf.
Circular T), from the data of the preceding month. If you take the leap
seconds out of UTC (in fact UTC(GPS), steered close to UTC(USNO)), you will
_not_ get TAI, just UTC(GPS)-34s...!
HTH,
Best regards,
Jean-Louis

Subject: [time-nuts] GPS time, UTC and TAI
Helo,
Re my last question.
I've read that GPS time is ahead of UTC time by 15 seconds and TAI time is
ahead of UTC by 34 seconds.
I need to generate time to a display based on TAI time.
Any ideas how I can do that with a normal M12M GPS receiver.
Martyn
