write a program that will set the time to 5:58

Hi anybody!

please help me!! i'm doing a project that focuses on time... i'm trying to figure out how to write a program that will set the time to 5:58 and have the "alarm" go off at 6;00. i absolutely can't figure out how to get the time setting to work!
thanks,

Which operating system and compiler.

Setting the time is an admin level operation on some systems for example

If you're using windows: SetSystemTime()
