# Time Calculator Quickly calculate when it's time to leave or when something will be over. Because the calculation of clock times is a bit cumbersome. At least if it is not carried out regularly. ## Examples Here, I want to be somewhere at 19:30 and have three things to do that take 20, 10 and 15 minutes: $ ./timecalc.sh 19:30 -20 -10 -15 19:30 19:10 -00:20 19:00 -00:10 18:45 -00:15 18:45 So I have to start at 18:45. Here, I want to know when I will be home after a movie that takes 128 minutes and starts at 20:00: $ ./timecalc.sh 20 128 20 20:00 22:08 02:08 22:28 00:20 22:28
