System time check

[digitalfredy]

Is your feature request related to a problem? Please describe.

I deployed auth for 35 users sending to them and I had hard time with one of them:

• I pre-configured 2FA per each user using auth and exporting the data using encryption
• Users imported the json file in auth and decrypt it using the password
• The user with the issue was not capable to login, wrong credentials while inserting the 2FA provided by auth

After a looong troubleshooting I found this user had his clock few minutes in advance and this why the 2FA was not working.

Describe the solution you'd like
Will be great if auth check the system configuration and inform the end user if his clock is not configured properly.

If the app can not check the system clock setup can check the time from an internet time server and validate if is the same provided by the system

Describe alternatives you've considered
If can not be automated a message is an alternative but is not good idea to disturb 95% of the users with this message addressed to the 5%

Additional context
User device: Android

Question: does ente auth connect to the internet for any other reason under normal conditions (i.e. already logged in)?
