Where can I find resources on minimum transfer times for Swedish stations?

I have been to Sweden by train from Germany multiple times and plan to do so again this summer. So far, I have planned my trips using DB’s HAFAS database on their website which is also where I booked part of my ticket.^[1]

However, I recently stumbled across a highly voted answer to a respectable question that discourages using HAFAS for a number of reason. Most relevant for me is the following (quoted from gerrit’s answer):

• It contains invalid connections. For example, in Sweden, each railway station has a minimum transfer time. HAFAS is not aware, so it might recommend a connection with a 10 minute change whereas the minimum transfer time is 15 minutes. Minimum transfer time in this case means that connections are guaranteed, so that tickets are replaced if a connection is missed. With a connection less than the minimum connection time, this guarantee will not work.

So far I have always had punctual trains in Sweden (or if they were late, it was always the final Swedish leg outbound to Copenhagen) so I have not yet had a problem. But to ease my peace of mind, I would like to know where I can find information on these minimum transfer times so that I can avoid unpleasant surprises.^[2]

In case there is no comprehensive database available, the stations I would most likely change trains at would be Malmö C, Alvesta and Nässjö C.

Notes:

[1]: For reasons unknown to me, DB only sells tickets to select Swedish stations, so I typically had two tickets for my journeys: One from Germany into Sweden (to Copenhagen in a single, rare case) and one onward ticket from the Copenhagen–Stockholm main line to my actual destination.

[2]: Unpleasant surprises mainly refers to being stuck at a train station because I missed a connection by a few minutes and now have to wait. As beautiful as Sweden is and as much of a trainspotter I am, it does typically get dull after the odd fifteen minutes …
