I have a string representing a unix timestamp (i.e. “1284101485”) in Python, and I’d like to convert it to a readable date. When I use time.strftime, I get a TypeError:

>>>import time
>>>print time.strftime("%B %d %Y", "1284101485")

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: argument must be 9-item sequence, not str

Use datetime module:

from datetime import datetime
ts = int("1284101485")

# if you encounter a "year is out of range" error the timestamp
# may be in milliseconds, try `ts /= 1000` in that case
print(datetime.utcfromtimestamp(ts).strftime('%Y-%m-%d %H:%M:%S'))

>>> from datetime import datetime
>>> datetime.fromtimestamp(1172969203.1)
datetime.datetime(2007, 3, 4, 0, 46, 43, 100000)

The most voted answer suggests using fromtimestamp which is error prone since it uses the local timezone. To avoid issues a better approach is to use UTC:

datetime.datetime.utcfromtimestamp(posix_time).strftime('%Y-%m-%dT%H:%M:%SZ')

Where posix_time is the Posix epoch time you want to convert

>>> import time
>>> time.ctime(int("1284101485"))
'Fri Sep 10 16:51:25 2010'
>>> time.strftime("%D %H:%M", time.localtime(int("1284101485")))
'09/10/10 16:51'

There are two parts:

1. Convert the unix timestamp (“seconds since epoch”) to the local time
2. Display the local time in the desired format.

A portable way to get the local time that works even if the local time zone had a different utc offset in the past and python has no access to the tz database is to use a pytz timezone:

#!/usr/bin/env python
from datetime import datetime
import tzlocal  # $ pip install tzlocal

unix_timestamp = float("1284101485")
local_timezone = tzlocal.get_localzone() # get pytz timezone
local_time = datetime.fromtimestamp(unix_timestamp, local_timezone)

To display it, you could use any time format that is supported by your system e.g.:

print(local_time.strftime("%Y-%m-%d %H:%M:%S.%f%z (%Z)"))
print(local_time.strftime("%B %d %Y"))  # print date in your format

If you do not need a local time, to get a readable UTC time instead:

utc_time = datetime.utcfromtimestamp(unix_timestamp)
print(utc_time.strftime("%Y-%m-%d %H:%M:%S.%f+00:00 (UTC)"))

If you don’t care about the timezone issues that might affect what date is returned or if python has access to the tz database on your system:

local_time = datetime.fromtimestamp(unix_timestamp)
print(local_time.strftime("%Y-%m-%d %H:%M:%S.%f"))

On Python 3, you could get a timezone-aware datetime using only stdlib (the UTC offset may be wrong if python has no access to the tz database on your system e.g., on Windows):

#!/usr/bin/env python3
from datetime import datetime, timezone

utc_time = datetime.fromtimestamp(unix_timestamp, timezone.utc)
local_time = utc_time.astimezone()
print(local_time.strftime("%Y-%m-%d %H:%M:%S.%f%z (%Z)"))

Functions from the time module are thin wrappers around the corresponding C API and therefore they may be less portable than the corresponding datetime methods otherwise you could use them too:

#!/usr/bin/env python
import time

unix_timestamp  = int("1284101485")
utc_time = time.gmtime(unix_timestamp)
local_time = time.localtime(unix_timestamp)
print(time.strftime("%Y-%m-%d %H:%M:%S", local_time)) 
print(time.strftime("%Y-%m-%d %H:%M:%S+00:00 (UTC)", utc_time))  

For a human readable timestamp from a UNIX timestamp, I have used this in scripts before:

import os, datetime

datetime.datetime.fromtimestamp(float(os.path.getmtime("FILE"))).strftime("%B %d, %Y")

Output:

‘December 26, 2012’

You can convert the current time like this

t=datetime.fromtimestamp(time.time())
t.strftime('%Y-%m-%d')
'2012-03-07'

To convert a date in string to different formats.

import datetime,time

def createDateObject(str_date,strFormat="%Y-%m-%d"):    
    timeStamp = time.mktime(time.strptime(str_date,strFormat))
    return datetime.datetime.fromtimestamp(timeStamp)

def FormatDate(objectDate,strFormat="%Y-%m-%d"):
    return objectDate.strftime(strFormat)

Usage
=====
o=createDateObject('2013-03-03')
print FormatDate(o,'%d-%m-%Y')

Output 03-03-2013

Other than using time/datetime package, pandas can also be used to solve the same problem.Here is how we can use pandas to convert timestamp to readable date:

Timestamps can be in two formats:

1. 13 digits(milliseconds) – To convert milliseconds to date, use:

   import pandas
   result_ms=pandas.to_datetime('1493530261000',unit='ms')
   str(result_ms)
   
   Output: '2017-04-30 05:31:01'
   

2. 10 digits(seconds) – To convert seconds to date, use:

   import pandas
   result_s=pandas.to_datetime('1493530261',unit='s')
   str(result_s)
   
   Output: '2017-04-30 05:31:01'
   

timestamp ="124542124"
value = datetime.datetime.fromtimestamp(timestamp)
exct_time = value.strftime('%d %B %Y %H:%M:%S')

Get the readable date from timestamp with time also, also you can change the format of the date.

In Python 3.6+:

import datetime

timestamp = 1579117901
value = datetime.datetime.fromtimestamp(timestamp)
print(f"{value:%Y-%m-%d %H:%M:%S}")

Output:

2020-01-15 19:51:41

Explanation:

• Line #1: Import datetime library.
• Line #2: Unix time which is seconds since 1970-01-01.
• Line #3: Converts this to a unix time object, check with: type(value)
• Line #4: Prints in the same format as strp.

import datetime
temp = datetime.datetime.fromtimestamp(1386181800).strftime('%Y-%m-%d %H:%M:%S')
print temp

Another way that this can be done using gmtime and format function;

from time import gmtime
print('{}-{}-{} {}:{}:{}'.format(*gmtime(1538654264.703337)))

Output: 2018-10-4 11:57:44

i just successfully used:

>>> type(tstamp)
pandas.tslib.Timestamp
>>> newDt = tstamp.date()
>>> type(newDt)
datetime.date

quick and dirty one liner:

'-'.join(str(x) for x in list(tuple(datetime.datetime.now().timetuple())[:6]))

‘2013-5-5-1-9-43’

You can use easy_date to make it easy:

import date_converter
my_date_string = date_converter.timestamp_to_string(1284101485, "%B %d, %Y")
