Dates are not checked properly

[JeremyKwok]

In the example above, debts can be set to be centuries before the current time, dates should be scrunitised before adding. Search does not check for invalid dates.

Team's Response

Instead of verify the validity of the date which we do not think it is necessary, we got verify the format of the date. For the search by date command, the program only checks if the date component has a substring of the content that the user want to find. It does not check for the validity and format of the date.
