[Digikam-users] Time & Date (Original) seconds value

[Den]

Sorry, don't know the reason for this. Perhaps it's to get there 
faster when you don't want to alter other metadata. It also gives you 
the possibility to change filename and file generation date (both are 
not metdata), which I did not find for the metadata way.

Btw.: I can change the seconds using your way. Weired... Might be a bug?
