Get local time based on coordinates

Question

I am programming an application that should give the local time based on the coordinates (lat&long) that you give it.

I only know of 2 methods to do that:

1st: Get the TimeZone Name, and then find its local time. 2nd: Use the Google API and receive the time as an offset and UTC not Local.

I decided to use the 1st method because seemed easier, so I decided to use the GeoTimeZone to get the Time Zone... Problem is that then I don´t know how to get the local time on that TimeZone... Here´s the code I wrote to get the TimeZone name.

string tz = TimeZoneLookup.GetTimeZone(lat, lon).Result;

variables lat & lon are of course the coordinates.

Thank you!

Edit: My question is how can I get the LocalTime on that TimeZone?

Answer 1

Here's my solution. It works offline (so no call to an api). It's fast and the packages are widely used and available on Nuget.

string tzIana = TimeZoneLookup.GetTimeZone(lat, lng).Result;
TimeZoneInfo tzInfo = TZConvert.GetTimeZoneInfo(tzIana);
DateTimeOffset convertedTime = TimeZoneInfo.ConvertTime(DateTimeOffset.UtcNow, tzInfo);
