I've never had a bank transfer that didn't take at least 3 days
SEPA is 3 days (and free) now, dunno about SWIFT etc, these are to expensive for myself and very low BTC-amounts (1-10).
SEPA 3 days? When I send a SEPA on a working day by 14:45, it appears in the other bank the next working day in the afternoon. So "3 days" is only if I make a transfer on Friday, then it appears on Monday. Otherwise just 1 day.
Bank transfers between banks in the UK go through in under 2 hours (Faster Payments). Usually under half an hour, I heard some people see it in the other bank within a minute or two, just to refresh the browser.
In Poland you can send transfers between banks through the BlueCash.pl system and it appears in the other bank within 10 minutes usually.
I think SEPA transfers are supposed to be at least as fast as local transfers, so banks here in Germany will usually take 3 days for SEPA transfers. (IIRC, I read this in wikipedia, if you want to verify it.)
