From the documentation of SQS, Max time delay we can configure for a message to hide from its consumers is 15 minutes - http://docs.aws.amazon.com/AWSSimpleQueueService/late
Cloudwatch is likely a better way to do it. You can use a createEvent API with the timer, and have it trigger either a lambda function or an API call to whatever comes next.
Another way to do is to use the "wait" utility in an AWS step function.

In any case, unless you are extremely sure you will never need anything more than 15 minutes, the SQS backdoor to add the delay seems hacky.
