pandas.Timestamp

class pandas.Timestamp(ts_input=<object object>, freq=None, tz=None, unit=None, year=None, month=None, day=None, hour=None, minute=None, second=None, microsecond=None, nanosecond=None, tzinfo=None, *, fold=None)

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_inputdatetime-like, str, int, float

Value to be converted to Timestamp.

freqstr, DateOffset

Offset which Timestamp will have.

tzstr, pytz.timezone, dateutil.tz.tzfile or None

Time zone for time which Timestamp will have.

unitstr

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, dayint
hour, minute, second, microsecondint, optional, default 0
nanosecondint, optional, default 0
tzinfodatetime.tzinfo, optional, default None
fold{0, 1}, default None, keyword-only

Due to daylight saving time, one wall clock time can occur twice when shifting from summer to winter time; fold describes whether the datetime-like corresponds to the first (0) or the second time (1) the wall clock hits the ambiguous time

New in version 1.1.0.

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')
