Firebase Functions : deploy version or timestamp (for logging)

What would be the best automatic available value to return (eg. in a HTTP function) that gives an unique indication of the current deployed version or timestamp of my functions (so not version of the node runtime)? Looking for e.g. a number or timestamp that gets incremented automatically when I do a new deploy of my functions.

I thought using this:

function currentFileTimestamp() {
  var stats = fs.statSync("./index.js");
  var mtime = new Date(stats.mtime);
  return mtime
}

But this always seams to return Tue Jan 01 1980 00:00:01 GMT+0000 Does the Firebase Admin API have a "current deployed version" timestamp or something that we could use?

I just deployed a test function to Google Cloud Functions using the python 3.10 runtime and can confirm that the environment variable is called K_REVISION as wheatazogg discusses in his post about nodejs10

import os

def testdeployfunction(data,context) :
    for name, value in os.environ.items() :
        print("{0}: {1}".format(name,value))
    return 'OK'

returns:

There are some alternatives that you can give it a try. On Node.js 10 runtime environment there is an environment variable - more information here - called K_REVISION, where you can find the value from the version of your Cloud Function.

For Python and older Node.js versions there is also an environment variable called X_GOOGLE_FUNCTION_VERSION that you can also check for the deployed version.

You can get more details on how to use them, with examples in this similar case here.
