Copy - Did Not Preserve Date Time of Directories

Copy - Did Not Preserve the Date & Time of the parent Directories?

Did a copy (backup) of some 36 GB of files from my HDD to an ESATA connected HDD.
For the copy I selected the option to Preserve dates and times of directories.

For some, 5 out of 50 or so, the parent directories were dated current instead of the date of the source. Subdirectories (if there were any) within these 5 were all dated correctly?

Actually when I first plugged in the ESATA I noticed that a couple of the existing directories there too were dated incorrectly, so this must have happened in the past also.

Using PB87 x86 on a Win7 x64 system.
Unsure if the same has happened with AS254?

Deleted the 5 from the ESATA, & copied them back over again from HDD & this time they were dated correctly?

OK, I think what made these different is that these were actually updates of existing directories rather then newly created at the destination.

IOW, these particular directories had existing, older, subdirectories that already existed on the ESATA, & when the newly found subdirectory was found on the HDD, the copy copied that, but I would have selected Skip (All) as the overwrite option for anything else.

So ... if that being the case, does it make sense that the destination directories are dated current rather then the date of the source? Perhaps it does?
