pandas.Timestamp

class pandas.Timestamp

Pandas replacement for datetime.datetime

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')

Methods

astimezone Convert tz-aware Timestamp to another time zone.
ceil return a new Timestamp ceiled to this resolution
combine(date, time) date, time -> datetime with same date and time fields
ctime Return ctime() style string.
date Return date object with same year, month and day.
day_name Return the day name of the Timestamp with specified locale.
dst Return self.tzinfo.dst(self).
floor return a new Timestamp floored to this resolution
fromordinal(ordinal[, freq, tz]) passed an ordinal, translate and convert to a ts note: by definition there cannot be any tz info on the ordinal itself

isocalendar Return a 3-tuple containing ISO year, week number, and weekday.
isoweekday Return the day of the week represented by the date.
month_name Return the month name of the Timestamp with specified locale.
normalize Normalize Timestamp to midnight, preserving tz information.
now([tz]) Returns new Timestamp object representing current time local to tz.
replace implements datetime.replace, handles nanoseconds
round Round the Timestamp to the specified resolution
strftime format -> strftime() style string.
strptime string, format -> new datetime parsed from a string (like time.strptime()).
time Return time object with same time but with tzinfo=None.
timestamp Return POSIX timestamp as float.
timetuple Return time tuple, compatible with time.localtime().
timetz Return time object with same time and tzinfo.
to_datetime64 Returns a numpy.datetime64 object with ‘ns’ precision
to_julian_date Convert TimeStamp to a Julian Date.
to_period Return an period of which this timestamp is an observation.
to_pydatetime Convert a Timestamp object to a native Python datetime object.
today(cls[, tz]) Return the current time in the local timezone.
toordinal Return proleptic Gregorian ordinal.
tz_convert Convert tz-aware Timestamp to another time zone.
tz_localize Convert naive Timestamp to local time zone, or remove timezone from tz-aware Timestamp.
tzname Return self.tzinfo.tzname(self).
utcfromtimestamp(ts) Construct a naive UTC datetime from a POSIX timestamp.
utcnow() Return a new Timestamp representing UTC day and time.
utcoffset Return self.tzinfo.utcoffset(self).
utctimetuple Return UTC time tuple, compatible with time.localtime().
weekday Return the day of the week represented by the date.
