Time Ago in Words for .NET C#

I saw the need for a C# version of the time_ago_in_words function in Ruby. I translated the code below into C# from my existing post I published for Ruby.

static string TimeAgo(DateTime time)
{
    DateTime startDate = DateTime.Now;
    TimeSpan deltaMinutes = startDate.Subtract(time);
    string distance = string.Empty;
    if (deltaMinutes.TotalMinutes <= (8724 * 60))
    {
        distance = DistanceOfTimeInWords(deltaMinutes.TotalMinutes);
        if (deltaMinutes.Minutes < 0)
        {
            return distance + " from  now";
        }
        else
        {
            return distance + " ago";
        }
    }
    else
    {
        return "on " + time.ToString();
    }
}


static string DistanceOfTimeInWords(double minutes)
{
    if (minutes < 1)
    {
        return "less than a minute";
    }
    else if (minutes < 50)
    {
        return minutes.ToString() + " minutes";
    }
    else if (minutes < 90)
    {
        return "about one hour";
    }
    else if (minutes < 1080)
    {
        return Math.Round(new decimal((minutes / 60))).ToString() + " hours";
    }
    else if (minutes < 1440)
    {
        return "one day";
    }
    else if (minutes < 2880)
    {
        return "about one day";
    }
    else
    {
        return Math.Round(new decimal((minutes / 1440))).ToString() + " days";
    }
}
