If dropping leap seconds is ultimately approved, we will need at least
two names for the new time scale. Perhaps something like this
(underscores are digits to be determined later):
TI: (Time, international) The time scale known as UTC from 19__ until
202_, and which ceased to observe leap seconds in 202_.
TAR: (Time, atomic, revised) The time scale equivalent to TI during
during and after 202_. Before 202_, the rules in effect in 202_ are
projected backwards. TAR = TAI - 3_ s
The TAR scale can be used in calculations in place of ET and TAI (with
suitable adjustments) if the offset between those time scales and post
202_ civil time is found to be inconvenient.
