Hi there,
I'm doing in *scratch* the following (with C-j at the end of the line):
(org-insert-time-stamp (org-read-date nil 'totime "8. März 2012"))
<2012-10-08 Mon>"<2012-10-08 Mon>"
(org-insert-time-stamp (org-read-date nil 'totime "8. März 1952"))
<1970-10-08 Don>"<1970-10-08 Don>"
(org-insert-time-stamp (org-read-date nil 'totime "1952-03-08"))
<1970-03-08 Son>"<1970-03-08 Son>"
So there a (german, and english - the last one) formated time is
translated correct for dates after 1970, but its wrong before that.
How can we fix that?
(this code is used in the google-contacts-to-org-contacts functions from
the google-contacts package)
Thanks,
Martin

See org-read-date-force-compatible-dates.

Thanks, that's the important hint. Even if I think this solution is for
stability by having less functionality. So maybe there should be found
a stable solution with full functionality?
Thanks,
Martin

This is a known issue: Unix was born in 1969 and time did not exist
before ;-) It's the equivalent of the big bang.
More seriously, the data structure used to indicate time and date in
Unix is 0 sometime in 1969 and runs out in 2037 (due to 32 bit integer
arithmetic), at least as far as org is concerned.
