Turning OFF Date on Today Screen

[a2k]

I'm creating a customization file and need the registry entry to disable the "Date" from appearing on the Today Screen. Not the calendar, but the "Date" the line that todays date.

For the life of me I'm unable to find this entry. I know I can do it via settings->Today->Items Tab... however, I'm in need of the specific registry flag to trigger it off.

Thanks!
