Bob,

TAI, UTC, and GPST (GPS System Time) is available here:

http://leapsecond.com/java/gpsclock.htm

I added one for you (Nixie display):

http://leapsecond.com/m/gpst.htm

If your new analog clock disagrees with these let me know. For more 
information on GPS Time (GPST), Galileo System Time (GST), and BeiDou 
Time (BDT), here's a short summary:

https://gssc.esa.int/navipedia/index.php/Time_References_in_GNSS

Note that GPST = UTC + 18 s (currently) but GPST = TAI - 19 s (always). 
So your analog clock will always be correct since TAI, GPST, GST, and 
BDT are unaffected by leap seconds in UTC.
