Hi Niklas,
When looking closer at the date- and time-formats for sv_SE I find a
lot of duplicates of YYYY-MM-DD
and YY-MM-DD. There are a few lets say questionable formats there
as well. When it comes to time-
formats. I really hope we at least can have HH.MM and MM.SS
As said, there can be only one TimeSeparator that is recognized by the
input scanner, which currently is ':', you may change that to '.' and
need to adapt at least the format codes that are used to edit existing
values, see current locale.dtd for details.
If you don't want to change the TimeSeparator you can still add HH.MM or
MM.SS formats to the already existing (use formatindex above 50 for
that), but those wouldn't be used to edit times, which may confuse
users.
Is it possible not to turn inputs on format MM.DD into dates in
Calc.
If there is no M.D DateAcceptancePattern defined then such input will
not yield a date. This was the main point of the change 
It is much more likely that it is
supposed to be a time value HH.MM?
Would be recognized as time only if the TimeSeparator would be '.'
instead of ':'
MM-DD is good to have accepted though. Not really sure if it's
possible.
With DateAcceptancePattern M-D yes.
I will have a closer look at the current formats and discuss them
locally. But that might take some
time so. I appended a few formats to the sv_SE.xml do you want a
patch, or how should i proceed?
Yes, a patch diff would be appreciated.
