Here is the relevant chunk of code:

gen date1=date(var1, "DMY")
gen date2=date(var2, "DMY")
drop var1 var2
g patientid = _n
reshape long date, i(patientid)
duplicates list patientid date
duplicates drop patientid date, force
tsset patientid date

When I run with my original data, I get the following error after the
tsset command.

tsset patientid date
repeated time values within panel

This may be due to the fact that, some patients may be discharged on
the same day of admission.

How to resolve this issue, if the patient is discharged on the same
day as admission.
