curl (on the unix/linux command line) can get/post to forms. A combination of curl, date and some regex should do what you want in a nice way. You could even set it as a cron job and make it do this every hour or whatever and spit the results into a csv file or something.
I realise, obviously, that you're unlikely to have a linux command line on your work machine but if you can either SSH in to a linux machine somewhere or simply have the script do the above and upload the CSV/text file somewhere where you can access it via http. Or there's always Cygwin.
I'd offer to do this for you but I absolutely lick balls at regex. I did make a script the other day to pull a random picture of the day from Wikipedia and set it as my wallpaper, which is doing
roughly the same sort of thing, but that pretty much reached the outer limit of my ability with regex. I'll link it in case it's helpful but I'm sure it's fucking awfully written.
