xarray.CFTimeIndex.to_datetimeindex

xarray.CFTimeIndex.to_datetimeindex#

CFTimeIndex.to_datetimeindex(unsafe=False)[source]#

If possible, convert this index to a pandas.DatetimeIndex.

Parameters:

unsafe (bool) โ€“ Flag to turn off warning when converting from a CFTimeIndex with a non-standard calendar to a DatetimeIndex (default False).

Returns:

pandas.DatetimeIndex

Raises:

ValueError โ€“ If the CFTimeIndex contains dates that are not possible in the standard calendar or outside the nanosecond-precision range.

Warns:

RuntimeWarning โ€“ If converting from a non-standard calendar to a DatetimeIndex.

Warning

Note that for non-standard calendars, this will change the calendar type of the index. In that case the result of this method should be used with caution.

Examples

>>> times = xr.cftime_range("2000", periods=2, calendar="gregorian")
>>> times
CFTimeIndex([2000-01-01 00:00:00, 2000-01-02 00:00:00],
            dtype='object', length=2, calendar='standard', freq=None)
>>> times.to_datetimeindex()
DatetimeIndex(['2000-01-01', '2000-01-02'], dtype='datetime64[ns]', freq=None)
