Something that is pretty common is to add a time to a date field, e.g an observation time (I saw Sasquatch at 7 AM on 7July).
But what if I saw Sasquatch on 28 June, and I'm just now getting around to adding the observation?
I pick June 28:
Then click on the time thingy and change it to 7 AM and now it's July 5! It seems the clicking on the time pick list is tied to the same mouse click event that runs "Today".
Now, if I set the time doo hickey to 7 AM FIRST, then I can pick June 28. Which doesn't seem very intuitive, nor can I find that in the online help, nor is there going to be any rational way I can explain that to the majority of my customers that are entering observation times as well as dates in a date field.
Since correlating the proof of the existence of Sasquatch to observation time (evening, when folks that believe in Sasquatch are 6 deep into a case of Natty Light) is key to my hypothesis, I really need the time to stick when I pick date....
