How to add days in epoch time in Python

#lssec -a lastupdate -s root -f /etc/security/passwd 2>/dev/null | cut -f2 -d=
1425917335

above command giving me epoch time I want to add 90 days in that time. how do I add days in epoch time?

datetime makes it easy between fromtimestamp, timedelta and timestamp:

>>> import datetime
>>> orig = datetime.datetime.fromtimestamp(1425917335)
>>> new = orig + datetime.timedelta(days=90)
>>> print(new.timestamp())
1433693335.0

On Python 3.2 and earlier, datetime objects don't have a .timestamp() method, so you must change the last line to the less efficient two-stage conversion:

>>> import time
>>> print(time.mktime(new.timetuple()))

The two-stage conversion takes ~10x longer than .timestamp() on my machine, taking ~2.5 µs, vs. ~270 ns for .timestamp(); admittedly still trivial if you aren't doing it much, but if you need to do it a lot, consider it another argument for using modern Python. :-)

Adding Dates and Times in Python, and timedelta, you can perform date and time addition/subtraction in python: DateTime myTime = new DateTime();; --Add 1 day; myTime. Add days to the current date; Add days to date in Python. In order to add days to a specific date we will have to use the below module: datetime module; In this module, there are many useful classes to manipulate date and time. We will use the following classes here: datetime; timedelta; Python program to add days to date. from datetime import datetime, timedelta specific_date = datetime(2019, 3, 5) new_date = specific_date + timedelta(21) print (new_date) Output: $ python codespeedy.py 2019

If the input is POSIX timestamp then to get +90 days:

DAY = 86400 # POSIX day (exact value)
future_time = epoch_time + 90*DAY

If you want to work with datetime objects then use UTC timezone:

from datetime import datetime, timedelta

utc_time = datetime.utcfromtimestamp(epoch_time)
future_time = utc_time + timedelta(90)

Don't use local time for the date/time arithmetic (avoid naive fromtimestamp(), mktime(), naive_dt.timestamp() if you can help it). To understand when it may fail, read Find if 24 hrs have passed between datetimes - Python.

You can you dateutil.parser as well:

since24Hours = datetime.utcnow() - timedelta(days=1)
since24Hours=dateutil.parser.parse(str(since24Hours))
since24Hours = since24Hours.strftime('%s')
since24Hours=int(since24Hours)*1000

Comments
  • my python 2.6 doesn't have >>> print(new.timestamp()) function getting error AttributeError: 'datetime.datetime' object has no attribute 'timestamp'
  • @Satish: Pre-3.3, you can cobble together .timestamp() using time.mktime(x.timetuple()). It's uglier (and you need to import time), but equivalent. Note, you may, depending on source of the timestamp and whether it's using UTC or local time, want to use utcfromtimestampand utctimetuple instead of the non-UTC functions given.
  • Side-note: 2.6? Really? 2.7 has been out for over five years!
  • I have imported both datetime and time but it didn't work, same error, any other work around?
  • @Satish: Wait, what? You couldn't possibly have the same error if you didn't call .timestamp(), and my suggestion was to replace new.timestamp() with time.mktime(new.timetuple()).
