I didn't find an answer to this elsewhere so I thought I would post it here. As I look at variable times I see a DateTime, but I see no way to just put in Time of day. Am I missing something? I have rules with things that happen the same time during the day, but occasionally I want to change those times. If I could put the time in a variable I wouldn't have to edit the rule, which can get dicey if I am editing conditions.
Maybe I answered my own question. I put in a time and left the date entry blank. It didn't seem to complain.
