Proc Traj: what if not everyone’s observations were observed at the exact same time points?

Hi all,

I'm starting to use Proc Traj. Does any one know how to deal with a dataset that not everyone’s observations were observed at the exact same time points?

I have no idea what proc traj does but you can always round SAS datetime values with something like:

newTime = round(time, '01:00:00't);

In this example, you would round to the nearest hour.
