Dealing with Dates and Times in Python

bookApplying Timezone to Datetime Object

Now we know about the variety of available timezones. How can we adjust it to a certain datetime object? How to make Python diff two datetime objects with different locations?

There are two approaches available. In this chapter, we consider the first. The algorithm is: create datetime object and save timezone within it using .localize() method. To do it, we will need to load timezone from pytz library. Then, we will need to create a timezone object, and then apply .localize() function to datetime object.

Please note, that this approach will simply 'put timezone label' on datetime object.

For example, let's represent all the mentioned steps.


              
1234567891011

            
# Load libraries and classes
import pytz
from pytz import timezone
from datetime import datetime

tz = timezone('Europe/Warsaw') # save timezone
dt = datetime(2021, 11, 1, 11, 25, 0) # create datetime object

# Apply timezone to dt
dt_tz = tz.localize(dt)
print(f"Datetime object with timezone: {dt_tz}")
copy

  1. Create timezone object named tz with value 'America/New_York'.
  2. Create datetime object named now with a current timestamp.
  3. Set tz timezone to now object and save it in now_tz variable.
