Description

The crontab expression for the current airflow scheduling task is 5 bits, instead of the usual 6 bits that are accurate to the second

Use case/motivation

airflow cycle scheduling task crontab does not support seconds, is there any method to support the scheduling task to run the scheduling task at 8:12 minutes 27 seconds every day

You can use custom timetable if you want. Look it up in the docs.

But be aware airlfow is usually used to run fine-grained tasks - that run for multiple seconds. And usually overhead on starting a task is counted in few seconds at least (depending on executor) - so there is no way to get second precision in execution. You are likely trying to use Airflow for something it was not created for.
