Convert Hex to display time and date

[Serge]

It depends how the data is stored. If the data represents a little-endian 64-bit integer, then you can convert it like this:

public DateTime HexToUTCDate(string hex)
{
    //Convert Hex To UTCDateTime
    long decValue = long.Parse(hex, System.Globalization.NumberStyles.HexNumber);
    DateTime dt = new DateTime(decValue);

    return dt;
}
