Daily Countdown to when BUS arrives. ( about 50 specific times )

Hello! I need a webscript .php where the resullt should look like this: Bus will arrive in x minutes, next bus in x minutes. And this script will use the servers clock and day. I must be able to add multiple times when the bus arrives in 3 different files. 1 for Monday-Friday ---- (maybe about 50 different times when bus arrives like 09:56, 11:32, 14:32 etc) 1 for Saturday ---(maybe about 50 different times when bus arrives like 09:14, 11:13, 14:36 etc) 1 for Sunday --- (maybe about 50 different times when bus arrives like 09:13, 11:22, 14:33 etc) this 3 files should be files where i can easy add this times when bus arrives. One last thing is that the countdown should look like this: [login to view URL] (Press layouts, and you will see a blue led style countdown) Thank you!
