No problem. It would not be exactly the same as election day. It would have the attributes of an advance polling day. The one way in which it would be the same as the general election day would be that the number and location of advance polling stations would be significantly expanded. However, the hours of operation would be the same hours of operation that would apply to an advance poll, namely, those from 12 until 8 p.m. in that time zone, wherever they were, rather than the staggered hours, for example.
There are also other legal attributes that relate to an advance poll that would apply. So with the exception of the number of locations, it would be an advance poll.
