Time error loading SSM maintenance windows

See original GitHub issue

I have the scheduler configured with several SSM maintenance windows, automatic startup during those windows is no longer working.

Scheduler default time zone is set to Australia/Brisbane, as was the maintenance window time zone. The following example error is logged by the EC2 scheduler at every invocation:

ERROR : Error loading ssm maintenace windows, (time data '2020-07-26T00:00+10:00' does not match format '%Y-%m-%dT%H:%MZ')

The schedules are then not found by the scheduler:

SSM maintenance window <window> used in schedule <schedule> not found or disabled

I’ve changed the Maintenance window time zone to UTC but this has not solved the issue. Any advice appreciated.

(Minor) Also note the typo in the error message - misspelling of ‘maintenance’

@rgoltz Yes this issue has been resolved in v1.4.0. For updating to the new version refer to the documentation, Review the cloudformation parameters, there is an additional Cloudformation parameter to Enable SSM Maintenance Windows update this based on your current usage.
