Hello Statlisters,

How do I make discrete times for my dates of visit (eg. I want the data to 
look like this:

id1 viralload cd4 etc.

t1    0
t2    1
t3    1

id2

t1    0
t2    1

id3

t1
t2
t3

I have been trying to find this in STATA help, my STATA book, and still cannot 
find how I need to change the dates to discrete times.
can you please help?

thanks so much,
martine
