featuretools.Timedelta

class featuretools.Timedelta(value, unit=None, delta_obj=None)

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’

__init__(value, unit=None, delta_obj=None)

Parameters

• value (float, str, dict) – Value of timedelta, string providing both unit and value, or a dictionary of units and times.

• unit (str) – Unit of time delta.

• delta_obj (pd.Timedelta or pd.DateOffset) – A time object used internally to do time operations. If None is provided, one will be created using the provided value and unit.
