Both quodlibet and exfalso accept only ISO-8601-style dates, which is a little bit too intolerant for my taste. It is nice to be warned about wrong date formats, but sometimes I like to enter date tags like: "1969-07-19..1969-07-20" "1969-07-19 — 1969-07-20" "1969-07-19 or 1969-07-20" Please change the behaviour of exfalso/quodlibet into a warning.
ID3 mandates ISO-8601-style dates. The QL developers are interested in being as standards-compliant as possible, and so we do not support writing broken tags; additionally, supporting non-standard date formats may require beefing up parsing and sorting code in several places. For these reasons, it is unlikely that incorrect date tags will ever be accepted (even with a warning). I recommend using a different tag (i.e. something other than 'date') to store the extended date ranges you describe, or perhaps only the second half of them. Steven
Quoting "Steven Robertson" <steven@strobe.cc>: I see. Let's close this bug then. OK, thanks for the hint!
tags 580932 + wontfix I'm marking it 'wontfix' instead, so in case someone else has the same idea later it will still appear on the bug page. regards, Christine
