polars.datatypes.Duration

class polars.datatypes.Duration(
    time_unit: TimeUnit = 'us',
)

Data type representing a time duration.

Parameters:
time_unit{‘us’, ‘ns’, ‘ms’}

Unit of time. Defaults to 'us' (microseconds).

Notes

The underlying representation of this type is a 64-bit signed integer. The integer indicates an amount of time units and can be negative to indicate negative time offsets.

__init__(
    time_unit: TimeUnit = 'us',
) → None
