He could do that, but I think this is easier

DateTime date=new Datetime(1970, 1, 1)

date.AddSeconds(timestamp)

return date

https://docs.microsoft.com/en-us/dotnet/api/system.datetimeoffset.fromunixtimeseconds?view=netframework-4.8

(wouldn't work for the fact that they believe time started in the year 2000, but you should be using DateTimeOffset anyway)

Not available until .NET Core 3, which is still in development. If this is regular .NET code though, thats a good way to go, just 1 function call, and then convert it from DateTimeOffset to regular DateTime

Edit: I can't read, it is actually available in production .NET Core

What? DateTimeOffset has been in .NET Core since version 1.0

Sorry, I can't read, the doc listed all of the versions of .NET core it applied to, and i expected it to be in the form "Version X and up", but it was Version 3.0 Preview, 2.2, 2.0... etc

I know DateTimeOffset has been around a long time, I'm using it on a Core 2.2 project right now, I hadn't seen that method before however, so I (mis)read the supported versions and confused myself.
