make python datetime include local time zone

python datetime timezone
python datetime set timezone
python datetime strptime
python datetime to string
python timedelta example
pytz
datetime now
python datetime now timezone

I wrote this python code but I am facing problems to make it work properly at the level of time zone. So basically the datetime.now() is not working as expected as it is not compliant to my local time (Paris local time) . Any idea how to sovle this please.

from datetime import datetime, timedelta
from airflow.operators import 
GoogleCloudStorageToGoogleCloudStorageOperator
copy_trm = GoogleCloudStorageToGoogleCloudStorageOperator(
        task_id='copy_file',
        source_bucket="source",
        source_object="input-files/*.orc",
        destination_bucket="destination",
        destination_object="output-files/recent",
        last_modified_time=datetime.now() - timedelta(days=1)

Best Regards

use pytz module

import pytz
tz = pytz.timezone('Pacific/Johnston')   #change it to your suitable timezone
ct = datetime.now(tz=tz)

8.1. datetime — Basic date and time types — Python 3.3.7 , Whether a naive object represents Coordinated Universal Time (UTC), local time, from datetime import timedelta >>> d = timedelta(microseconds=-1) This makes it possible to specify format string for a date object when using str.format(). Most of the time zones are offset from Coordinated Universal Time (UTC), the world’s standard for time zone. In order to get the current time of different time zones, we will be using the pytz python library. How to get the current time ? In order to get the local time, we can use the time module. Some important functions of the time module

If you want to know your current timezone name. It is possible with below code:

import datetime
dt = datetime.datetime.now()
dt.astimezone().tzname()

Output:

'IST'

You can send time in UTC format as:

dt.astimezone().utcnow()

make python datetime include local time zone, use pytz module import pytz tz = pytz.timezone('Pacific/Johnston') #change it to your suitable timezone ct = datetime.now(tz=tz). In this code, you use tz.UTC to set the time zone of datetime.now () to the UTC time zone. This method is recommended over using utcnow () because utcnow () returns a naive datetime instance, whereas the method demonstrated here returns an aware datetime instance.

With the standard library, requires the numerical offset

If you have the numerical offset of your timezone (compared to UTC) then you use the standard library:

>>> from datetime import datetime, timezone
>>> datetime.now().strftime("%c (%Z)")
'Wed Feb 13 23:00:06 2019 ()'
>>> datetime.now(tz=timezone.utc).strftime("%c (%Z)")
'Wed Feb 13 22:00:11 2019 (UTC)'
>>> datetime.now(tz=timezone(timedelta(hours=2))).strftime("%c (%Z)")
'Thu Feb 14 00:00:20 2019 (UTC+02:00)'

Though since the offset can change throughout the year (e.g. with daylight saving time), it is recommended to use a named timezone.

With dateutils, using the host timezones database

The Python documentation on timezone points to the dateutil.tz package which will use the timezone database from the machine it runs on. The pytz package on the other hand comes with a bundled timezone database.

I would personally recommend the dateutil package since the database already exists on the running machine. As long as the machine is kept up-to-date (as any server and PC should) you are good to go.

>>> from dateutil.tz import gettz  # GNU/Linux and macOS
>>> # Or, on Windows: from dateutil.tz.win import gettz
>>> datetime.now(tz=gettz("Europe/Paris")).strftime("%c (%Z)")
'Wed Feb 13 23:00:58 2019 (CET)'
>>> datetime.now(tz=gettz("Asia/Taipei")).strftime("%c (%Z)")
'Thu Feb 14 06:01:27 2019 (CST)'

Working with Datetime Objects and Timezones in Python, To make a datetime object offset aware, you can use the pytz library. First, you have to instantiate a timezone object, and then use that timezone object to "localize" a datetime object. Localizing simply gives the object timezone information. In this article, you will learn to get today's date and current date and time in Python. We will also format the date and time in different formats using strftime() method. There are a number of ways you can take to get the current date.

Using Python datetime to Work With Dates and Times – Real Python, Python's standard library includes a module called time that can print the This way, you'll always be able to convert the local time to UTC. For applications requiring aware objects, datetime and time objects have an optional time zone information attribute, tzinfo, that can be set to an instance of a subclass of the abstract tzinfo class. These tzinfo objects capture information about the offset from UTC time, the time zone name, and whether daylight saving time is in effect.

Working with Time and Time Zones in Python, You know that the time zone is Europe/Paris or Central European Time import datetime import pytz timestring = "2017-05-30T23:51:03Z" # Create datetime timestamp = "1496181063" # Gives you the date and time in local� import datetime naive = datetime.datetime.now() naive.tzinfo > None. To make a datetime object offset aware, you can use the pytz library. First, you have to instantiate a timezone object, and then use that timezone object to "localize" a datetime object. Localizing simply gives the object timezone information.

Time zones | Django documentation, Python's datetime.datetime objects have a tzinfo attribute that can When time zone support is disabled, Django uses naive datetime objects in local time. import datetime now = datetime.datetime.now() a timezone for a time with no associated date does not make sense. The object representation of Python time may or may not take your time zone into account. There are two ways to convert a float representing seconds to a struct_time: UTC; Local time; To convert a Python time float to a UTC-based struct_time, the Python time module provides a function called gmtime(). You’ve seen gmtime() used once before in

  • Looking at the airflow documentation, airflow.apache.org/… I think last_modified_time is not expected to be passed as a parameter.
