Ummarrrgh. click_gettimeofday() and click_jiffies can go backwards if the time is changed, yes. I'm not sure how wise it would be to fix this problem. Xwrits, for example, keeps track of when time goes backwards. But in the xwrits solution, gettimeofday()'s result has no absolute meaning (it's mostly like elapsed time). How big a problem is this for y'all? E
