Thanks so much for your fast response. I am in the US and I did forget to set the Daylight Savings in my preferences.

I hope that's the only problem... I tried doing an automatic listing after I posted my question on this forum, and that didn't work either. I just set the DST and scheduled the listings again, i hope it works this time! But shouldn't they be showing up in my events? They were successfully scheduled, but still not appearing under Events. Is that normal?
UPDATE: My first scheduled listing went through! Thanks so much for your help!!!
