 You should have a variable named `currentDateFormat` that holds the current date in the format `Current Date and Time: <ddd> <MMM> <dd> <yyyy> <HH>:<mm>:<ss> <TIMEZONE>`.
 
 ```js
-const expectedDate = new Date();
 const expectedDateString = `Current Date and Time: `;
 assert.include(currentDateFormat, expectedDateString);
 
 const currentTimestamp = new Date(currentDateFormat.replace(expectedDateString, '')).getTime();
-const expectedTimestamp = expectedDate.getTime();
-assert.approximately(currentTimestamp, expectedTimestamp, 1000);
+const expectedTimestamp = new Date().getTime();
+assert.approximately(currentTimestamp, expectedTimestamp, 2000);
 ```
 
 You should log the value of `currentDateFormat` to the console.
