(Fatwa: 159/90/D=1433)
(1) You are not employees of your immediate boss rather you are the employees of government department. Hence it is necessary to follow the rules and regulations of government. If that department does not allow writing 3 hours in the register instead of 2.5 hours then it is not lawful for you to do so. And it shall not be halal to take the salary of extra 30 minutes.
(2) It is not lawful to do so as it is mentioned under no. 1.
