Note, I wanted to switch SNS over entirely to aws go SDK v2, as it uses both v1 and v2, but this PR is already quite large and I'll switch over to v2 in a separate PR

Overall LGTM. Left a nit comment. I can trigger the test pipeline

[james03160927]

can we define a new constant in globals.go file the format of the time we will store the firstSeenTime, to prevent inconsistency in the future?

then, we can replace the usage of time.RFC3339 here and below in set function

Thanks, I updated this in sns.go, and found occurrences in ec2_vpc.go and ecs_cluster.go. I can push these changes to a new PR if you'd like to keep the context to SNS in this PR. Either works for me.

FTR, I have tested the change in our environment and have verified that it fixes #480 for us. Thanks.
