Dear all:

Hello.

I’m a user of time zone data in IANA. Lately I found a problem when I used it in Android O system.

external\icu\tools\update-tzdata.py

I used the tool in the below path to deal with the data tzcode2017c.tar.gz. Then the error occurred.

Finally I found the way to solve it. It seemed that africa file and backzone file have a duplicated data:

# South Sudan

Zone      Africa/Juba         2:06:24 -               LMT       1931

                                                2:00        Sudan   CA%sT  2000 Jan 15 12:00

                                                3:00        -              EAT

I deleted one in backzone, then it worked.

Now I’m wondering if this is mistake. And what are the influences?
