The change was intentional made upstream: https://github.com/eggert/tz/commit/1b99dcde6342dd10969041b32b00b813d4f4a36e ("Remove many invented abbreviations in 'asia'"). The upstream maintainer invented ICT: https://github.com/eggert/tz/commit/1b99dcde6342dd10969041b32b00b813d4f4a36e#commitcomment-22025554
I am marking this bug as Won't Fix.
