ts1 = timeseries(rand(1,4096));
%official approach. uses indices
ss2a = getsampleusingtime(ts1, 1, 2048);
ss2b = getsampleusingtime(ts1, 2049, 4096);
ss2a, ss2b
  timeseries

  Common Properties:
            Name: 'unnamed'
            Time: [2048x1 double]
        TimeInfo: tsdata.timemetadata
            Data: [1x1x2048 double]
        DataInfo: tsdata.datametadata

  timeseries

  Common Properties:
            Name: 'unnamed'
            Time: [2047x1 double]
        TimeInfo: tsdata.timemetadata
            Data: [1x1x2047 double]
        DataInfo: tsdata.datametadata
%another approach. Uses times with first time being 0
ss1a = resample(ts1, 0:2047);
ss1b = resample(ts1, 2048:4095);
ss1a, ss1b
  timeseries

  Common Properties:
            Name: 'unnamed'

        TimeInfo: tsdata.timemetadata
            Data: [1x1x2048 double]
        DataInfo: tsdata.datametadata
