How to overcome missing timezone implementation in the Mono WASM runtime

Question

If I try to print DateTime.Now.TimeOfDay in Uno, Wasm, and UWP will print two different times. Wasm in UTC and UWP in current culture. How can I make sure in both cases I get Local time?

Answer 1

I ran into this issue as well. To resolve use javascript. When wasm is detected use Uno.Foundation.WebAssemblyRuntime.InvokeJS.

    var getTime = Uno.Foundation.WebAssemblyRuntime.InvokeJS("javaTime()");

In a javascript file in your wasm WasmScripts folder

function javaTime() 
{
    var date = new Date();
    return date.toLocaleTimeString();
}
