Get a comprehensive canonical list of TZLabels #5

Closed ysangkok closed 8 months ago

ysangkok commented 10 months ago

Since I started deduping TZLabels, I chose a bunch of arbitrary names. This could really be done more systemically.

% cabal repl -b tzdata

Loaded GHCi configuration from /tmp/cabal-repl.-12638/setcwd.ghci
ghci> :m +Data.Time.Zones.DB
ghci> :set -XOverloadedStrings

For some labels, it's fine, I think:

ghci> fromTZName "Asia/Tel_Aviv"
Just Asia__Jerusalem

But for others, it's a bit weird:

ghci> fromTZName "Indian/Reunion"
Just Asia__Dubai

Not sure if there is a better canonical label than Dubai.

Closing since I removed deduping with release 2024a.
