Determining Amazon EC2 instance creation date/time

Question

Is it possible to determine (via boto) when a particular EC2 instance was created?

http://boto.readthedocs.org/en/latest/ref/ec2.html doesn\'t seem to be giving any

Answer 1

As shown here:

http://boto.readthedocs.org/en/latest/ref/ec2.html#module-boto.ec2.instance

Each Instance object has an attribute called launch_time which contains a IS08601 datetime string representing when the instance was launched.

In boto, you could do something like this:

import boto.ec2

conn = boto.ec2.connect_to_region('us-west-1')
reservations = conn.get_all_instances()
for r in reservations:
    for i in r.instances:
        print('%s\t%s' % (i.id, i.launch_time)
