polars.datatypes.Datetime#
- class polars.datatypes.Datetime(time_unit: TimeUnit = 'us', time_zone: str | timezone | None = None)[source]#
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.
