polars.datatypes.Datetime

class polars.datatypes.Datetime(time_unit: TimeUnit = 'us', time_zone: str | timezone | None = None)

Data type representing a calendar date and time of day.

Parameters:

time_unit{‘us’, ‘ns’, ‘ms’}

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

time_zone

Time zone string, as defined in zoneinfo (to see valid strings run import zoneinfo; zoneinfo.available_timezones() for a full list). When used to match dtypes, can set this to “*” to check for Datetime columns that have any (non-null) timezone.

Notes

The underlying representation of this type is a 64-bit signed integer. The integer indicates the number of time units since the Unix epoch (1970-01-01 00:00:00). The number can be negative to indicate datetimes before the epoch.
