rhysd/actionlint v1.7.12 on GitHub

Support the timezone configuration in on.schedule with checks for IANA timezone string. See the documentation for more details. Note that actionlint starts to embed the timezone database in the executables from this version so the binary sizes slightly increase. (#641, thanks @martincostello)
```

  schedule:
    # ERROR: The timezone is not a valid IANA timezone string
