Hi,

I just received a dataset which has a 'date variable in a format I
haven't come across before. I need help with reformatting this date
variable so that it's similar to other date variables I have in the
dataset.

The date variable reads like this when I 'summarize' and 'decribe' it:



sum  inskdat_new

    Variable |       Obs        Mean    Std. Dev.       Min        Max
-------------+--------------------------------------------------------
 inskdat_new |    305358    818.8836     613.712          1       2441

. des  inskdat_new

              storage  display     value
variable name   type   format      label      variable label
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
inskdat_new     long   %d          inskdat_new
                                              enlistment date


-As you can see from the above,  the date has a min value of 1 that
 corresponds to 1997-06-23 and a maximum value of 241 that corresponds
to 2009-02-04.



-How do I reformat this variable so that it's a 'float' with %d display
format and reads like 19feb2010 when I tabulate it and with stata time
(when checking the minimum & maximum values when I summarize the
variable)??

Any help will be much appreciated!

Thanks,

/Amal.
