Probably not.  I've got a dehumidifier in my darkroom that pretty much runs constantly this time of year.  The last time I printed (successfully) was at the end of winter, so it was relatively dry then, but I am guessing not all that different from now in my room.
I have not kept track of drying time, but it has varied from 30 minutes to half a day (when I ran out of time one evening).

 Any chance there is a change in humidity or moisture when coating and exposing?  Drying time?

Best Wishes,
