Need documentation/example to make jmespath query on datetime object.

Currently all the boto3 documentation show date element as datetime() object.e.g.

{
    'Contents': [
        {
            'Key': 'string',
            'LastModified': datetime(2015, 1, 1),
            'ETag': 'string',
  .....
}

There is little documentation mentioned how to deal with the datetime object when using jmespath query.

I contacted AWS support about this and after some wrong starts they gave me this which works:

import boto3 
s3 = boto3.client("s3")
s3_paginator = s3.get_paginator('list_objects_v2')
s3_iterator = s3_paginator.paginate(Bucket='mytestbucket')
filtered_iterator = s3_iterator.search(
    "Contents[?to_string(LastModified)>='\"2016-12-27 08:05:37+00:00\"'].Key"
    )
for key_data in filtered_iterator:
    print(key_data)

However because you’re providing a string you have to be careful with the format. I haven’t tested this exhaustively so there may be combinations that don’t work.

A clean version where you can have the filter date to be dynamic:

    my_region = os.environ.get("AWS_REGION", "us-east-1")
    session = boto3.Session(region_name=my_region)
    client = session.client("ec2")
    paginator = client.get_paginator('describe_snapshots')
    page_iterator = paginator.paginate(
        Filters=[
            {
                "Name": "status",
                "Values": [
                    "completed",
                ],
            },
        ],
        OwnerIds = ['self'],
    )

    filter_date = str(datetime.today() - timedelta(days=1))
    filtered_iterator = page_iterator.search(f"Snapshots[?to_string(StartTime) >= '\"{filter_date}\"']") 
    for k in filtered_iterator:
        pprint.pprint(k)
