I has in string format, timestamp 1593339378252
, i need convert this, to a normal human date-20.06.2020
I try this code
var timestamp = Convert.ToInt64(dateFrom);
// Format our new DateTime object to start at the UNIX Epoch
System.DateTime dateTime = new System.DateTime(1970, 1, 1, 0, 0, 0, 0);
// Add the timestamp (number of seconds since the Epoch) to be converted
dateTime = dateTime.AddSeconds(timestamp);
but if i try convert to int32,16,64 i get System.ArgumentOutOfRangeException
