No error message to tell you what is wrong with the schedule date/time

[wapisai]

Does not tell you exactly what you need to put in for the date and time in the app (the user guide does but that is not convenient to go all the way there)(should just put the format in the help message "Invalid command format!
schedule: Adds a lesson to the student identified by the index number used in the last person listing. Parameters: INDEX (must be a positive integer) l/ [LESSON]
Example: schedule 1 l/ 20-02-2002|10:00"

and does not tell you what went wrong when inputting the date/time
