# pandas.Timestamp

class `pandas.``Timestamp`

  Pandas replacement for python datetime.datetime object.

  Timestamp is the pandas equivalent of python’s Datetime and is interchangeable with it in most cases. It’s the type used for the entries that make up a DatetimeIndex, and other timeseries oriented data structures in pandas.

  Parameters:

  ts_input : datetime-like, str, int, float

  > Value to be converted to Timestamp.

  freq : str, DateOffset

  > Offset which Timestamp will have.

  tz : str, pytz.timezone, dateutil.tz.tzfile or None

  > Time zone for time which Timestamp will have.

  unit : str

  > Unit used for conversion if ts_input is of type int or float. The valid values are ‘D’, ‘h’, ‘m’, ‘s’, ‘ms’, ‘us’, and ‘ns’. For example, ‘s’ means seconds and ‘ms’ means milliseconds.

  year, month, day : int

  > New in version 0.19.0.

  hour, minute, second, microsecond : int, optional, default 0

  > New in version 0.19.0.

  nanosecond : int, optional, default 0

  > New in version 0.23.0.

  tzinfo : datetime.tzinfo, optional, default None

  > New in version 0.19.0.

  Notes

  There are essentially three calling conventions for the constructor. The primary form accepts four parameters. They can be passed by position or keyword.

  The other two forms mimic the parameters from `datetime.datetime`. They can be passed by either position or keyword, but not both mixed together.

  Examples

  Using the primary calling convention:

  This converts a datetime-like string

      >>> pd.Timestamp('2017-01-01T12')
      Timestamp('2017-01-01 12:00:00')

  This converts a float representing a Unix epoch in units of seconds

      >>> pd.Timestamp(1513393355.5, unit='s')
      Timestamp('2017-12-16 03:02:35.500000')

  This converts an int representing a Unix-epoch in units of seconds and for a particular timezone

      >>> pd.Timestamp(1513393355, unit='s', tz='US/Pacific')
      Timestamp('2017-12-15 19:02:35-0800', tz='US/Pacific')

  Using the other two forms that mimic the API for `datetime.datetime`:

      >>> pd.Timestamp(2017, 1, 1, 12)
      Timestamp('2017-01-01 12:00:00')

      >>> pd.Timestamp(year=2017, month=1, day=1, hour=12)
      Timestamp('2017-01-01 12:00:00')
