I see a problem if we wait till then for the change over.
Y2K caused a mess in 1999 as people have to scramble to fix the problem in time.
Now we see 2038 time problem not being fixed till 2017 when it could have been fixed long ago. Talk about waiting to the last decade or two. Now people are talking as if we have fixed the t_time problem.
Have we not learnt from history!
Next we will send the last million or so years fixing the time to 128 bits when we could fix the problem now!
Will we never learn?
