Dear Stata users. 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?


    gen t2 = cond(_n<=185705, date(t,"DMY"), date(t,"MDY"))
