For anyone having trouble with the date appearing incorrect in there sms timestamps, I had the same problem and created a tweeked entry that will resolve this problem and will allow you to maintain the date over time on the taskbar as well keep the timestamps in there correct format. Using the same registry location and procedure mentioned earlier in this post
HKEY_LOCAL_MACHINE\nls\overrides Create a String value Name = SSDte but instead use Value = M/dd/y ' ' two spaces between the y and The last ' ' to push the date to the right to allow the "OK" not disturb or clash w/ the date. I'm not sure if this will conflict with any other programs for the 800w but i hope this will help anyone else like myself which had the same problem you can thank me later
