Invalid Timestamp returned for check in some cases

[comp615]

Describe the bug
Using this action, sometimes the checks are not correctly run

To Reproduce
Steps to reproduce the behavior:

1. Make a change using the job below
2. Check results in Apollo. Sometimes nothing is returned and the date range is shown as invalid

Environment

jobs:
  check_schema:
    name: check schema
    runs-on: ubuntu-latest
    timeout-minutes: 5
    steps:
      - uses: actions/checkout@v2
      - name: Apollo Schema check
        uses: iansu/apollo-schema-check-action@v2
        with:
          graph: [[REDACTED]]
          localSchemaFile: 'server/graphql/schema.graphql'
          serviceName: [[REDACTED]]
          validationPeriod: P1W
          key: ${{ secrets.APOLLO_KEY }}
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Additional context
Continuing to look at this and see if there's any commonalities. Seems likely it might be an issue on the Apollo side of things since I don't know what would have changed here

From Apollo support, they claim that the seconds for from should be negative (i.e. “-604800”). So maybe will try swapping that? Going to run into the how do I test issue again.
