Programming a world clock with RTC ds3231

Yeah, that is intentionally commented out until install the buttons (later today).

But the way you did it comments out much more than what I showed....
including all the code up to line 163 where it finally sees the */

/* routines

This is why using /* */ to "comment" out code is a bad thing to do.

hat other editior would you suggest?

I use linux so I use gvim with arduino syntax highlighting for .ino and .pde files.

You must still be having issues with your "commenting" out of code.
When I remove your stray /* on line 125 of the code you posted, the code compiles just fine.
