text: Title: [FEATURE] More time parameters on make_simpleseries
  Body: Good morning, 
  
  currently make_simple_series only generates daily data, this is not fit for my example where I reed a higher granularity. Given that in order to generate dates it is using pd.date_range, I want to add those parameters in the generation of the time dimension. 
  
  Alaso the possibility to set the time as an index or even to create the object as pd.Series if input. 
  
  Thank you, 
  Gonxo
