return a new Timestamp floored to this resolution

Parameters
freqa freq string indicating the flooring resolution
ambiguousbool, ‘NaT’, default ‘raise’
  • bool contains flags to determine if time is dst or not (note that this flag is only applicable for ambiguous fall dst dates)

  • ‘NaT’ will return NaT for an ambiguous time

  • ‘raise’ will raise an AmbiguousTimeError for an ambiguous time

New in version 0.24.0.

nonexistent‘shift_forward’, ‘shift_backward, ‘NaT’, timedelta, default ‘raise’

A nonexistent time does not exist in a particular timezone where clocks moved forward due to DST.

  • ‘shift_forward’ will shift the nonexistent time forward to the closest existing time

  • ‘shift_backward’ will shift the nonexistent time backward to the closest existing time

  • ‘NaT’ will return NaT where there are nonexistent times

  • timedelta objects will shift nonexistent times by the timedelta

  • ‘raise’ will raise an NonExistentTimeError if there are nonexistent times
