I forgot to mention that the program preview is correct for the waterings but it is off for which day it thinks it is. I believe it is a time zone issue that Ray corrected on the regular OpenSprinkler javascript a few months ago and was due to being a long way from GMT (GMT+10 in my case). If I set the url as gp?d=date+1 then it thinks that is today but it can’t place the red line properly.
