Hi estateselluh,
If you have noticed that your scheduled listings posted one hour earlier than you intended, then the clock in your account is still set to reflect daylight savings time.
To correct this problem, please go to Auctiva -> My Account(tab) -> Account Settings, uncheck the box next to "Add 60 minutes for daylight savings time." and then click the "Update Account Preferences" button.
Once you have adjusted this setting, the clock within your Auctiva account will have kicked it's speed addiction.
