class_docstr: Represents differences in time.
  
  Timedeltas can be defined in multiple units. Supported units:
  
  - "ms" : milliseconds
  - "s" : seconds
  - "h" : hours
  - "m" : minutes
  - "d" : days
  - "o"/"observations" : number of individual events
  - "mo" : months
  - "Y" : years
  
  Timedeltas can also be defined in terms of observations. In this case, the
  Timedelta represents the period spanned by `value`.
  
  For observation timedeltas:
  >>> three_observations_log = Timedelta(3, "observations")
  >>> three_observations_log.get_name()
  '3 Observations'
