[Therion] Therion date data delimiter

Good morning I've just inherited some Therion survey data that includes dates defined: date 1985 2 16 (as opposed to date 1985.2.16) A cursory look suggests it is working, in that no errors or warnings are reported, and Aven seems to be interpreting the dates of the surveys exported from Therion. The Therion Book suggests that . is the only valid delimiter in this position - no mention of using a space. Is there any problem with using a space as the date delimiter? Regards Bruce
