Cron job doesn´t work as scheduled

Bug

Body

I have the following piece of a script to execute an .YML in actions, that is scheduled to run at 02:50 UTC every Thursday:

name: Automation class

on:
schedule:
- cron: '50 02 * * 4'
workflow_dispatch:

jobs:
reserva:
runs-on: self-hosted # Cambiado para correr en el runner autohospedado

steps:
- name: Checkout repository content
  uses: actions/checkout@v2

- name: Setup Python
  uses: actions/setup-python@v2
  with:
    python-version: '3.x'

However, all the actions I have scheduled have a big delay of about 35 minutes past midnight, even if I scheduled 3 hours before midnight. I don´t know what the reason is that the cron job doesn´t follow the scheduled time. Here is the last log of execution:

2024-11-21T03:45:13.6827908Z Current runner version: '2.320.0'

Hi @Pvillarroelo,

Please refer to the following GitHub Docs page: Events that trigger workflows - Schedule

The schedule event can be delayed during periods of high loads of GitHub Actions workflow runs. High load times include the start of every hour. If the load is sufficiently high enough, some queued jobs may be dropped. To decrease the chance of delay, schedule your workflow to run at a different time of the hour.

I hope this helps.

Kind Regards,
Ruben
