I'm not sure about .nl, you could try asking in the cctld forum of namepros.
It has been awhile since I have tried to catch anything on the drop myself that ends with .com
Anything decent has much competition and if it makes it to the drop, it gets caught by a dropcatching company. From what I remember they drop anytime between 1100 and 1400 PST (Pacific). Hopefully somebody else can give you more info.
If there is one specific name that you are after, I'd suggest trying to get it before it drops.
