The Netherlands is on CET, not GMT. So polls close at 8PM GMT, if I understand correctly.
It should be point out that:
North America had their Spring Time Change last week, Europe changes their clocks in late March.
There is normally a 6 hour time difference between the Eastern Time Zone (North America) and Central Europe. But since North America had already 'Spring Forward', there is now a 5 hour difference (for about 3 weeks) between these two time zones.
Right now: It just after 6 pm in the Netherlands, polls close in 3 hours.
