I don't have access to Stata 9 but will make various guesses: something like 

gen date = cond(_n <= 185705, date(t, "dmy"), date(t, "mdy"))

seems called for.

I'm using stata 9  and windows XP. I need to format
a date variable in order to be able to define a panel dataset. My time
variable (t) is in the format day/month/year, but the tricky thing is
that this format changes for a specific set of observations. From
1-185705 the time variable is dd/mm/yy, but from 185706-360288 the
format is mm/dd/yy. I imported the data from excel using insheet.

Before knowing about the existence of the two different formats of
time in my variable I used: generate t2=date(t,"dmy"), but then a lot
of missing values appeared. What do you think it is plausible to be
used so I can get my new time variable (t2) that considers the
differences in formats already present in my stata dataset?
