RE: st: dates
I guess at least a few people may be confused by this thread.
The problem is _not_ the order of the elements month, day,
year, as Stata's -date()- function is capable of handling
various orders. The issue is Stata's assumption that
the dates come with separators. Rodrigo's examples show
his problem better than his notation, which includes separators.
In my experience, dates without separators (run-together
dates) are fairly common. I have heard some individuals comment
that in particular fields they are actually the norm!
-todate- has been a work-around lurking on SSC since 2001
while StataCorp gets round to supporting them.
Several FAQs discuss dates. This may be the one that Rodrigo
