Odd directory size

[Howard Robinson]

This is possibly a silly question but here goes.
The following is the two entries /var/spool for the mailscanner
queues.
drwxr-xr-x    2 root     mail      1220608 Oct  2 15:56 mqueue
drwxr-xr-x    2 root     mail        24576 Oct  2 15:56 mqueue.in
All the other directories here and a random selection of other
directories seem to have a size of 4096.
Is this a sign of an error or has it something to do with the
volume of files it once held? Currently mqueue.in has 1 or 2 files
waiting to be scanned and mqueue had about ~100 files all small.
Also the date changes, does this reflect the last time the
directory was used? In NT and WS2000 the date & time reflect
when it was created. Is this a Redhat Linux feature?
