 We can adjust the time series data to reflect this structure in each `System`:
 
-  - `transform_single_time_series!(sys_DA, 48, Hour(1))`
-  - `transform_single_time_series!(sys_RT, 12, Minute(15))`
+  - `transform_single_time_series!(sys_DA, Hour(48), Hour(24))`

 Now we can put it all together to define a `SimulationSequence`
