What Time is it in ... ?

As you might notice, the previous method simply labels to datetime timezone. The second approach is to convert existing datetime objects with no timezone to a certain timezone.

Let's consider the same datetime object as in the previous chapter, but this time with the second approach. The algorithm is the next:

  1. Create datetime object with no timezone;
  2. Create timezone object with a certain timezone name (optional);
  3. Apply .astimezone() method to datetime object with timezone object as an argument.

# 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 dt_tz = dt.astimezone(tz) # convert dt to tz timezone # Testing print(f"Saved time: {dt}") print(f"Converted time: {dt_tz}")
copy

There you can see a clear difference: not only timezone was saved, but time was adjusted to timezone. Let's try to complete the task! Please note, that code is compiling on a dedicated server with GMT.

Use the second approach to convert datetime object with a current timestamp to tz timezone:

  1. Set 'America/New_York' timezone in tz.
  2. Apply method to datetime object now to convert it to tz timezone.
