Does it really matter what time to take OPK’s?

I just started my fertile window yesterday and took a opk test but I took it at 5pm. Last month I took them around noon every day during my fertile window. So I was just wondering if it changes the accuracy of them if you take them at different times of day? Would it be okay to take one at noon today rather than 5pm?
