thelastmessiha opened a new issue, #24359:
URL: https://github.com/apache/airflow/issues/24359
### Apache Airflow version
2.2.5
### What happened
I've set the core default_timezone and default_ui_timezone values to
America/Los_Angeles which successfully makes the scheduler respect the local
Pacific timezone, however, when I create a task using the DateTimeSensor in a
dag with schedule_interval='@daily' and would like that particular task to wait
until 3am Pacific using the below code, it still appears to be using UTC rather
than Pacific and completes as soon as it's scheduled, at midnight Pacific,
rather than waiting until 3am Pacific. I believe this is happening at midnight
Pacific because the dag itself is bound by the schedule_interval='@daily' which
is in Pacific time and when it checks if it's 3am UTC yet, it evaluates to the
past and executes.
start = DateTimeSensor(
task_id='start',
target_time='{{ data_interval_end.replace(hour=3) }}',
dag=dag,
)
One way to get this working as expected is to change it to the following,
which explicitly specifies the timezone, but this is tedious as it would need
to be used everywhere and I'd like to be able to develop all dags without
having to think about timezone since everything is Pacific timezone-based:
start = DateTimeSensor(
task_id='start',
target_time='{{ data_interval_end.replace(tzinfo="America/Los_Angeles",
hour=3) }}',
# timeout=1500,
dag=dag,
)
### What you think should happen instead
I think it makes sense to automatically make all behaviors related to
timezone match the scheduler's timezone unless otherwise explicitly specified.
### How to reproduce
set the core default_timezone and default_ui_timezone values to
America/Los_Angeles.
Observe the tasks executions and note the time that the DateTimeSensors are
completing.
