docs: def _adjust_bin_edges(datetime_bins, offset, closed, index, labels):
      """This is required for determining the bin edges resampling with
      daily frequencies greater than one day, month end, and year end
      frequencies.
  
      Consider the following example.  Let's say you want to downsample the
      time series with the following coordinates to month end frequency:
  
      CFTimeIndex([2000-01-01 12:00:00, 2000-01-31 12:00:00,
                   2000-02-01 12:00:00], dtype='object')
  
      Without this adjustment, _get_time_bins with month-end frequency will
      return the following index for the bin edges (default closed='right' and
      label='right' in this case):
  
      CFTimeIndex([1999-12-31 00:00:00, 2000-01-31 00:00:00,
                   2000-02-29 00:00:00], dtype='object')
  
      If 2000-01-31 is used as a bound for a bin, the value on
      2000-01-31T12:00:00 (at noon on January 31st), will not be included in the
      month of January.  To account for this, pandas adds a day minus one worth
      of microseconds to the bin edges generated by cftime range, so that we do
      bin the value at noon on January 31st in the January bin.  This results in
      an index with bin edges like the following:
  
      CFTimeIndex([1999-12-31 23:59:59, 2000-01-31 23:59:59,
                   2000-02-29 23:59:59], dtype='object')
  
      The labels are still:
  
      CFTimeIndex([2000-01-31 00:00:00, 2000-02-29 00:00:00], dtype='object')
  
      This is also required for daily frequencies longer than one day and
      year-end frequencies.
