When replying to an e-mail, the original date is not quoted completely
When I reply to an e-mail, Opera Mail quotes the original mail, starting with something like:
"Am .05.2015, 13:50 Uhr, schrieb Sekretariat:"
That should read
"Am 20.05.2015, 13:50 Uhr, schrieb Sekretariat:"
How do I get the program to include the day?
Right-click on the message and choose "view all headers and message". Make sure the date header value is correct. If it is, it's probably a locale issue/bug. Make sure the locale is set correctly in your OS and in Opera and restart. If nothing helps, I guess it's just a bug. Opera Mail has been discontinued, so if it is a bug, you're out of luck.
