How can I split time series in a half?

The time series is consisted of 4096 samples.

I want to split it by two of 2048 samples.

[Walter Roberson]

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

  Common Properties:
            Name: 'unnamed'
            Time: [2048x1 double]

            Data: [1x1x2048 double]
