There was a thread on the 323 forum about this. D-Link said that they would address this, and for now the workaround was to set the unit to a different time zone.
Can you link to that thread? I have a suspicion you're confusing two different issues - the DNS-323 has (in fw 1.06), and as far as I can recall, has always had a checkbox to enable/disable daylight saving time - I believe the thread you're thinking of may have referred to an issue relating to the "new" daylight saving time "change dates", causing the time to be incorrect.
Where I am, DST is not used, so I invariably have to find that check box and disable it.
