ingress_expiry not within expected range error in candid ui. Motoko language, console prompted a breaking change on running dfx deploy

Question

I was following a course tutorial to create a small decentralized bank application using dfinity's internet computer. the main.mo file is as follows:

import Debug "mo:base/Debug";
import Float "mo:base/Float";
import Time "mo:base/Time";

actor DBank {
  stable var currentValue: Float = 300;
  stable var startTime = Time.now();
  Debug.print(debug_show(currentValue));

  public func topUp(amount: Float){
    currentValue += amount;
    Debug.print(debug_show(currentValue));
  };

  public func withdraw(amount: Float){
    let tempValue: Float = currentValue - amount;
    if(tempValue >= 0){
        currentValue -= amount;
        Debug.print(debug_show(currentValue));
    } else{
      Debug.print("Withdrawal amount is more than Balance.")
    }
  };

  public query func checkBalance(): async Float{
    return currentValue;
  };

  public func compound() {
    let currentTime = Time.now();
    let timeElapsedNS = currentTime - startTime;
    let timeElapsedSec = timeElapsedNS / 1_000_000_000;
    currentValue := currentValue * (1.01 ** Float.fromInt(timeElapsedSec));
  };

}

The Candid Interface was working until I changed the the data type of currentValue from Nat to float. It showed a warning when i ran dfx deploy on the terminal:
user***@hp:~/ic-projects/dbank$ dfx deploy
Deploying all canisters.
All canisters have already been created.

WARNING!
Candid interface compatibility check failed for canister 'dbank'.
You are making a BREAKING change. Other canisters or frontend clients relying on your canister may stop working.

Method checkBalance: func () -> (float64) query is not a subtype of func () -> (nat) query
Do you want to proceed? yes/No
yes

I do not have the original warning, I tried to recreate it so float64 and nat might be interchanged.

On deployment the Candid UI shows this: An error happened in Candid canister: Error: Server returned an error: Code: 400 (Bad Request) Body: Specified ingress_expiry not within expected range: Minimum allowed expiry: 2023-02-06 19:04:14.511184689 UTC Maximum allowed expiry: 2023-02-06 19:09:44.511184689 UTC Provided expiry: 2023-02-06 19:25:14.339 UTC Local replica time: 2023-02-06 19:04:14.511189299 UTC

I was thinking whether this could be a problem from Time module but couldn't find much about it, as the module documentation page has been removed.

Looked up the ingress_expiry problem and tried it's solutions: the local machine's time is correct and in sync with the actual time. Using wsl1 in vscode, it is the latest version i suppose as running wsl --update shows you have the latest version

The breaking change warning in the question description was orginally prompted for the checkBalance() function but I could not include anything worthwhile.

Answer 1

In my case, below command worked.

sudo hwclock -s

Answer 2

Your Ubuntu clock is not synchronized with system clock. Write this command in terminal of ubuntu sudo apt-get install ntp .This command will synchronize your ubuntu time with your system. Make sure your system has correct time and date.

Answer 3

This was caused because of unsyncronized time between Ubuntu and system time. On running this sudo hwclock -s on the Ubuntu terminal and redeploying the app will eliminate the error.
