1217305 - Some city names in tz.json do not match system tzdata

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::Settings, defect)

Description

[Samael Wang [:freesamael] (away for now)]

Attachment: tzdata-names.txt

When user picks a timezone in Settings, gaia composes the timezone name with region/city defined in tz.json [1]. The system (gonk), however, inherently relay on /system/usr/share/zoneinfo/tzdata from AOSP [2]. Hence the composed timezone name has to match one defined in tzdata, otherwise the timezone is not recognized and will fall back to UTC time.

Some examples are "São_Tomé", "N'djamena", "Chișinău", etc.

I've extract the name list of B2G kitkat (which actually comes from IANA tzdata2013h [3]). We should verify tz.json to ensure it matches the names used in tzname-names.txt I attached.

:tedders said he's planning to switch us over to use ICU timezones, but I can't find the bug in which he said that.

Ted, what's you plan here?

I believe you're referring bug 1201254. I've taken a quick look, the Olson timezone name mapping inside the file looks good.
