There was this exchange
Rajesh Tharyan:
The command gen adate=date(date,"dmy"), where date is a string variable
works fine in stata9. However, it generates missing values in stata10.
Nick Cox:
In Stata 10, try "DMY".  
Rajesh Tharyan:
Is there a good reference on how little things like this have changed
between version 9 and 10? 
Nick Cox:
I am not sure whether this is flagged anywhere. It's arisen
several times on the list since Stata 10. No one pays much 
attention until it bites them!  
Get an overview of all changes from version 9 to 10 by:
  . help whatsnew9to10
This is a pretty long list. To see about current syntax for date
  . help date
This leads to a very large help file describing the new date_and_time
variables. It may be a bit overwhelming.
I think users would benefit from a shorter FAQ describing the changes
in date handling from version 9 to 10. 
Note that you can use version control to allow version 9 syntax:
  . version 9
  . gen adate=date(date,"dmy")
  . version 9: gen adate=date(date,"dmy")

Hope this helps
