How to convert nanoseconds to local DateTimeOffset in C#?

How can I convert nanoseconds to Datetimeoffset?

I tried date time

long nanoseconds = 1449491983090000000;
DateTime epochTime = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Local);
DateTime result1 = epochTime.AddTicks(nanoseconds / 100);

DateTime epochTimfe = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
DateTime result2 = epochTime.AddTicks(nanoseconds / 100);

Both result1 and result2 are giving me GMT time. i.e.,

12/7/2015 12:39:43 PM

I verified that from here

Can anyone help me how to convert nanoseconds to DateTimeOffset ?

You could just construct an instance of DateTimeOffset in UTC, add the nanoseconds, then call ToLocalTime to get the local version.

long nanoseconds = 1449491983090000000;
var epochTime = new DateTimeOffset(1970, 1, 1, 0, 0, 0, TimeSpan.Zero);
var utc = epochTime.AddTicks(nanoseconds / 100);
var local = utc.ToLocalTime();
