alex-astronomer opened a new issue, #30605:
URL: https://github.com/apache/airflow/issues/30605
### Apache Airflow version
2.5.3
### What happened
Mexico senate voted to change their rules on DST last year in October.
Mexico's timezones (for the most, including Mexico City) are now running at
UTC-6. As of last year at this time, Mar 21st was the date that Mexico would
bring their clock forward for DST.
`pendulum` depends on `pytzdata`. The latest version of `pytzdata` is from
2020, so it doesn't have this information in it.
Therefore, theoretically and as tested, Airflow has the wrong time for
Mexico now.
### What you think should happen instead
All timezones should be up to date.
### How to reproduce
On a virtualenv with just Airflow installed, and everything else default,
run this script:
```
import pendulum
local_tz = pendulum.timezone("America/Mexico_City")
print(pendulum.now(local_tz))
```
This will display the old time before the change was in place.
### Operating System
Docker Linux
### Versions of Apache Airflow Providers
n/a
### Deployment
Virtualenv installation
### Deployment details
Everything default.
### Anything else
[Here](https://github.com/sdispater/pendulum/issues/700) is the related
issue on `pendulum`'s Github.
