Solve the following python programming problem given the following code:
def _read(self, last_pass = False) : 
    '
        Generator method that returns next portion of data

        :type last_pass: bool
        ' 
    def mcs2sec(val) : 
        return (int ((int (val) / 1000.0)) / 1000.0) 
if self.stats_reader : 
        self.stats_reader.read_file (last_pass) 
if ((not self.csvreader) and (not self.__open_fds ())) : 
        self.log.debug ('No data to start reading yet') 
        return 
self.log.debug ('Reading: %s', self.filename) 
    self.fds.seek (self.offset) 
    for row in self.csvreader : 
        label = row ['label'] 
        rtm = mcs2sec (row ['elapsed']) 
        ltc = mcs2sec (row ['Latency']) 
        cnn = mcs2sec (row ['Connect']) 
        if (row ['opretcode'] != '0') : 
            error = strerror (int (row ['opretcode'])) 
            rcd = error 
else : 
            error = None 
            rcd = row ['responseCode'] 
tstmp = int ((float (row ['timeStamp']) + tstmp)) 
        concur = 0 
        (yield (tstmp, label, concur, rtm, cnn, ltc, rcd, error, '')) 
self.offset = self.fds.tell () 

    
    

    Fix the buggy line: tstmp = int ((float (row ['timeStamp']) + tstmp))
assistant
#Here is Python program to fix the buggy line: tstmp = int ((float (row ['timeStamp']) + tstmp))
.

tstmp = int ((float (row ['timeStamp']) + rtm))
