How do I find out the timestamp when a Python application was deployed to GAE?

I need to know the timestamp when my application was deployed to the GAE server. At run time.

Of course, I could create some Python constant in the deployment script. But is there an easier and more correct way to achieve the goal?

(I wouldn't want to use a data store for this.)

Wrap appcfg.py

in a shell script. appcfg.py update

Save the current time before launching , possibly adjusting for your time zone, if necessary, in a file marked as a resource. You can open and read this file from the deployed application.



Alternatively, let the script replace the current time directly in the code, eliminating the need to open the file.

I don't believe there is a GAE API that gives you access to a deployment timestamp.



The closest functionality is the CURRENT_VERSION_ID

environment variable, but this gives you access to version

that specified in app.yaml

, not timestamps.
