Hi Tobias,
From the look of it, you are using protection manager, all those goofy snapshot directory names...When protection manager was released, someone chose a ":" as part of the snapshot name, which is great on Unix, not so much on Windows.
Run this command on the DFM host: dfm option set pmUseSDUCompatibleSnapshotNames=Yes and it will start using "_" which is acceptable to both Unix and Windows. The default protection manager naming will be fixed automatically and include date and time in the snapshot name, making it possible for you to see exactly what you are asking for.
The bad news is, all the existing snapshots will remain with the bad naming until they roll off. For me, some of those were 30 to 40 days. Aborzenkov's link will allow you to see those existing bad ones the way you want, by adding another field, "accessed", to the Windows display in explorer.
