Dear all,

I've tried to bring it in character-format (as.charachter())
followed by
as.POSIXlt() but I get an error message, that the character
string is not in
a standard unambiguous format, although the date is of format
yyyy-mm-dd
(what is standard format according to R reference manual).

Thank you very much for any usefull hint!
There seems to be someting fishy about 1 january 1970, I think it
is a bug in Windows:
as.POSIXlt("1970-01-01")
Error in fromchar(x) : character string is not in a standard unambiguous
format
