This seems to be more of a difference between how each of the functions works so might be considered more of a feature request. Unlike day, wday and yday who all report themselves in an integer form in the number of days since their respective dates - qday reports itself in the number of seconds since the period turn. It seems as though this behavior should be able to be matched to the other functions. Since qday does not have any parameters, I might suggest adding parameters to it and leaving the current behavior (report out in seconds) as the default. See below for what I mean.
