A way to provide clock_skew_in_seconds

[fatadel]

The method verify_token -

firebase-admin-python/firebase_admin/_token_gen.py

Line 392 in 6d826fd

verified_claims = google.oauth2.id_token.verify_token(

- has an additional parameter called clock_skew_in_seconds - https://.com/googleapis/google-auth-library-python/blob/87cd2455aca96ac3fbc4a8b2f8e4c0bba568a70b/google/oauth2/id_token.py#L114.

However, it is not possible to provide this parameter when verifying ID tokens -

firebase-admin-python/firebase_admin/auth.py

Line 194 in 6d826fd

def verify_id_token(id_token, app=None, check_revoked=False):

I have been recently having issues where validating tokens failed from time to time with a message "Token used too early", where the timestamps were having a difference of 1-3 seconds. I have ed the admin SDK with clock_skew_in_seconds=10 argument and the issue disappeared. I do understand that my server's time synchronization is the problem in first place but being able to provide existing parameters would also be extremely helpful.

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

@fatadel could you share how you ed the admin SDK to add clock_skew_in_seconds=10?
I am having the same issue.

Closing this since it was resolved in #714.
