MATLAB scripting, please help

Write a script Time that will prompt the user to enter the current time as a vector of two elements hours minutes) and the time zone (HST, AKST, PSTMST, CSTand EST) as a string. Based on the values entered, the script must calculate and display the standard time in the other time zones based on the conversion of the given Table. If another time zone is entered, the program must display a message of invalid entry and ask the user to try again. You can assume a 24-hour clock, so for example if the standard time in CST is [12 40), it would be 1340] in MST, etc. see the Table below. The script must not display any negative times, for example if the HST time is 1:10 am it must be 24 in KST and 23 in PST, etc. Using fprintf, the output must be displayed as Time in HST is 1:40 , Time in KST is 24:40, Time in PST is 23:40, Time in MST is 22:40, Time in CST is 21:40, Time in EST is 20: 40, Use your script to find the following times in all time zones: a ) 2:30 pm in HST b) 10:50 pm in EST c) 2:20 am in KST d) 4:40 am in HST e) 1:10 am in FST (FST is not a predefined time zone) Table: Standard time and daylight saving time Time Zone Standard Time 1 Hawait Time Zone HST UNC-.00) Alaska Time Zone IRST CUTC-09200) Pacific Time Zone PST (UTC-08:00) : Mountain Time Zone MST (ICOz00m Central Time Zone cost wriC 0600) (- Eastern Time Zone EST (UTC-05:00) Write a script Time that will prompt the user to enter the current time as a vector of two elements hours minutes) and the time zone (HST, AKST, PSTMST, CSTand EST) as a string.
