Zoneinfo doesn't model the differences between flavours of UT, or
indeed any sub-second effects.  So yes, it can handle the name change,
presuming that we treat TI as a flavour of UT for this purpose.
(While it's certainly not a flavour of UT for many other purposes,
not least the plain definition of UT.)
