Don't know for sure but the following may help you: http://maia.usno.navy.mil/ http://www.iers.org/MainDisp.csl?pid=36-9 http://maia.usno.navy.mil/ser7/finals.daily http://maia.usno.navy.mil/search/search.html My recollection is that using VLBI, UT1 is measured to sub-millisecond even microsecond levels. For example, yesterday UT1-UTC was -148.709 ms, today it is -149.996 ms, and tomorrow it will be -151.172 ms. /tvb _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
