Increase valid starting times for github report

The github actions that run as a part of our nightly
reports often start later than expected. We previously allowed
for a 20 minute delay but now we can allow for a 59 minute delay.
59 minutes is the longest possible delay that should still not cause
confusion when reporting the results.
