[ubuntu] Sometimes Date and Time doesn't show up

view story

http://ubuntuforums.org – I upgraded to 13.10 and noticed sometime the date and times doesn't show up in the indicator bar. Sometimes the machine boots and it is there and sometimes it is not. Is there anyway of resolving this? I did a google search and couldn't find any resoultion. Everythign talks about installing the date and time indicator, which is already installed. Is this just a bug that will be resolved with an update in the future? (Hardware)
