longstringToNanoseconds(String time)
Convert a string representing a time to the corresponding long. 
long result = 0L;

    for (int i = buffer.length() - dot - 1; i < 9; i++)
        buffer.append("0"); 
    int nbDecimals = buffer.substring(dot + 1).length();
    if (nbDecimals > 9)
        buffer.delete(buffer.substring(0, dot + 1 + 9).length(), buffer.length());
    long seconds = (dot > 0) ? Long.parseLong(buffer.substring(0, dot)) : 0;
    seconds = Math.abs(seconds);

    result = seconds * 1000000000 + nanosecs;
} catch (NumberFormatException e) {
return result;
