AWS Cloudwatch Rule Schedule Cron Expression to Skip 2 Hours in a Day

Question

I want to trigger an AWS Lambda function, using Cloudwatch Rules and the requirement is as follows.

• Condition 1: Trigger Daily
• Condition 2: Every 5 mins
• Condition 3: It should NOT trigger between 11PM and 1AM every day (Maintenance Window).

I read the documentation on crons and am unable to come up with a Cron expression to fulfill condition 3. I came up with the following expression.

0/5 ## * * ? *

How can I fulfill condition 3 mentioned above? I have left it as ## on the cron expression. I am well aware of the timezones.
