in reply to How to compare arrays? (xmms alarm clock)

though I didn't know it until the minutes were equal and the hours were not...apparently, it only compares the last element.

The == operator demands scalar context of its arguments. The comma in scalar context returns the rightmost argument. So the comma didn't make a list, but evaluated the stuff for side effects and kept the last (single) value only.

Look at mapcar to iterate the two lists in tandum.
