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
