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
variables:
 
  . 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")
 
or
 
  . version 9: gen adate=date(date,"dmy")

 
Hope this helps
