[William.Hatheway]

I am having an interesting result with my wrf output times for D01 vs D02

D02 is as expected but I cannot figure out why D01 outputs the files not on the top of the hour when the interval is very 60min. I have attached my namelist.input for reference

I can't say for sure, but it could have to do with the time_step = 54. Try setting that to something that divides evenly into 60 minutes - like "=45" to see if that makes any difference.
