This is a bit difficult to follow, but a difference in date-times is
itself an elapsed  time, not a date-time.

If -clock()-  was used to compute date-times, the results in
milliseconds need to be divided by 60 * 60 * 1000 to get a result in
hours.

I created a cat with delay (time2-time1), which has the 1 jan 1960, I don't really know how to change that, still it's not the matter. I would like to keep only the patients for how delay is < or = to 5 hours, should I write 5 hrs in a SIF time? How do I convert? Didn't work so far. Thanks for your help. Kim
