GitHub Actions Schedule Misalignment

This is a Git-style (e.g. GitHub Actions) scheduled trigger. Let’s break it down:

on: schedule: Tells the workflow to run on a calendar schedule, not just on push or pull-request events.

- cron: '0 * * * *' A standard five-field cron expression:

┌──────── minute (0)
│ ┌────── hour (*, i.e. every hour)
│ │ ┌──── day-of-month (*, i.e. every day)
│ │ │ ┌── month (*, i.e. every month)
│ │ │ │ ┌ day-of-week (*, i.e. every day of the week)
│ │ │ │ │
0 * * * *

→ Runs at minute 0 of every hour (i.e. at 00:00, 01:00, 02:00…23:00 UTC), every day.

But the comments above it say:

Run every hour from 05:00–13:00 UTC, Mon–Fri 05:00–13:00 UTC = 13:00–21:00 Beijing time (UTC+8)

That intention (weekdays, only those hours) would actually require a more specific cron, for example:
```
on:
  schedule:
    - cron: '0 5-13 * * 1-5'
```
which means:
- at minute 0,
- during hours 5 through 13 UTC,
- on days Monday (1) through Friday (5).
In Beijing time (UTC+8), that indeed corresponds to 13:00–21:00 local time, weekdays.

In short:

As written ('0 * * * *'), it will fire every hour on the hour, 24×7.
The comments describe a weekday-only, 05:00–13:00 UTC window—if that’s what you want, change the cron to include 5-13 for the hour field and 1-5 for the weekday field.
