Did you try to do similar search with other abbreviations?

For example, i found (in 'europe'): AMT - it marked as 'invented', none 
of the first  20 matches time zone abbreviation, but it still in 
database. When it will be removed?

I have just tried:

North America: HDT, HST (America/Adak), AKDT, AKST (America/Nome), HST 
(Zone Pacific/Honolulu)

None of 50 first matches for these searches are not about time (skip 
timezone converter sites, they are based on tzdata).
I think, the same can be said about _any_ abbreviation.

For HDT even timezoneconverter sites are not in search results.

Did you still find google search is reasonable instrument to detect if 
abbreviation is widely-used?

The same can be said about _any_ abbreviation.

Then just remove abbreviations completely.But you somehow think that 
they are important to some people and unimportant to others.
