Oswald is right that it should work to truncate times to the second for 
comparison. (I guess time() + 1 is a shortcut to the same outcome.) 
Might be some trouble to do that portably. There's the standard C 
library function difftime()...

Seems better to do that than to hit the filesystem through stat().
