[Android][Net6/7] TimeZoneInfo StandardName/DaylightName does not displays abbreviations anymore

[takla21]

Description

Since net6.0-android, StandardName & DaylightName does not return abbreviations. Instead it returns the full name.

Reproduction Steps

I've made a small uno project containing both a Xamarin version & net6/7 version that checks all TimeZoneInfo and display TimeZoneInfo.Local info to the page.

• Download this sample TimeZoneSample.zip
• Open it on visual studio 2022
• Go to the NET folder
• Deploy on android (you can also change net version in the csproj)
• Look for logs in the console

Alternatively, you could simply add those logs on any net6/7 or xamarin app

var timeZones = TimeZoneInfo.GetSystemTimeZones();
foreach (var tz in timeZones)
{ 
    Console.WriteLine($"timezone {tz}= StandardName: {tz.StandardName}, DaylightName: {tz.DaylightName}");
}

Expected behavior

Console logs: logs_expected.txt

Here's the result on my android xamarin sample app provided above

Actual behavior

With the loggin in the expected section, I have this on my android net6/7 project logs_actual.txt

Here's the result on my net6/7 android sample provided above

Regression?

I'm not 100% sure the specific .NET version, but on xamarin it's not an issue.

Known Workarounds

N/A

Configuration

• net6.0-android, net7.0-android
• Tested on Android 11

Other information

On net6.0-ios, it's still displaying abbreviations for StandardName & DaylightName.

I had this on my net6/7 android sample provided above

Regression?

I'm not 100% sure the specific .NET version, but on xamarin it's not an issue.

Known Workarounds

N/A

Configuration

• net6.0-android, net7.0-android
• Tested on Android 11

Other information

On net6.0-ios, it's still displaying abbreviations for StandardName & DaylightName.

Issue Details

---

Description

Since net6.0-android, StandardName & DaylightName does not return abbreviations. Instead it returns the full name.

Reproduction Steps

I've made a small uno project containing both a Xamarin version & net6/7 version that checks all TimeZoneInfo and display TimeZoneInfo.Local info to the page.

• Download this sample TimeZoneSample.zip
• Open it on visual studio 2022
• Go to the NET folder
• Deploy on android (you can also change net version in the csproj)
• Look for logs in the console

Alternatively, you could simply add those logs on any net6/7 or xamarin app

var timeZones = TimeZoneInfo.GetSystemTimeZones();
foreach (var tz in timeZones)
{ 
    Console.WriteLine($"timezone {tz}= StandardName: {tz.StandardName}, DaylightName: {tz.DaylightName}");
}

Expected behavior

Console logs: logs_expected.txt

Result on the android xamarin sample app provided above

Actual behavior

With the loggin in the expected section, I have this on my android net6/7 project logs_actual.txt

Nothing yet, but it is on @mdh1418's list to investigate.

Hi @takla21, I believe the change in behavior is expected. The .NET 6 effort included a unification that affected the base class libraries, so now the Android implementation follows .NET libraries implementation in lieu of the mono/mono BCL implementation that is seen in Classic Xamarin.Android. I believe you might be able to see the abbreviations for the StandardName and DaylightName properties if you use GlobalizationMode.Invariant.

Is there a particular reason you need to have abbreviations for these properties? As the documentation (showing the specific .NET 6 docs) for TimeZoneInfo.StandardName and TimeZoneInfo.DaylightName exemplify a full name and do not mention providing abbreviations, I believe any desire to have abbreviations instead in a non GlobalizationMode.Invariant environment will be an API proposal instead.

[takla21]

Hi @mdh1418, so essentially, we need to display the timezone on our app. In our case, it's easier to fit the abbreviation rather than its full name.

Fortunately, we've worked around it by using another library, https://www.nuget.org/packages/TimeZoneNames, to get the abbreviation. So, if you're saying that it's supposed to behave that way on net6, I guess we can close it. Although, if I recall correctly, on iOS, it still displays the timezone as abbreviated. Does this mean that there should be a bug on iOS instead?

[mdh1418]

It might indeed be a bug on iOS as we use our own version of ICU to grab information, so the appropriate data to get the full name for StandardName and DaylightName might have been filtered out. I'll have to investigate that. Thanks for pointing it out!
