Perhaps for FISH a solution could be found when trying harder.

But there are other KIO slaves that have no idea about the timezone or the 
time offset of the dates in the files, for example zip and tar, but also 
floppy or mac. Probably the only thing that could be told is that the time 
was local on the system having written those files.

Similar to other office documents. The dates/times are supposed to be local 
but the document does not give any clue in which timezone the dates/times 
were written, or at least with which time offsets.

May be we misunderstood us here. I was talking about a possible change of 
Konqueror, assuming that KIO slaves would be changed too, to allow KDateTime 
to be passed. (I do not think that it is planned now.) So there would no need 
over converting to seconds-to-epoch.


Have a nice day!
