Any news on it @steveisok @mdh1418 ? |
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 Is there a particular reason you need to have abbreviations for these properties? As the documentation (showing the specific .NET 6 docs) for |
|
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? |
|
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! |
|
Closing this issue as it is the current expected behavior for Android, will create an iOS issue after confirming the bug. |
