I was having problems the last few days with the current time date "sol" for the mer on the NASA and mmb It was almost 30 sols ahead of the images I was getting. I was just about to post something to see if anyone else had this problem when I realized I had inadvertently changed my calendar some time a month ahead. I now realize the NASA and mmb calculate the current time/sol on Mars by reading your computer date. Knowing this makes for some fun stuff. If you want to know what sol the rovers will be at on a certain date just change the date on your computer and refresh. weird. Learn something new each day. hope this didn't mess up my last modified dates on mmb.
