So "ls" is not showing the modification time in localtime, this behaviour is different than every other system I own. I would have guessed this has something to do with this, until you mentioned the skew clocks. R.

Do you build on a network file system? Do they have a "scratch" partition you can use, which is on a local disk? What you see has to do with "skew clocks" on the fileserver vs the CPU you use.
