Broken widgets?

My boss pointed out to me the other day that his widgets don't work anymore. He clicks on one (they do update on the dashboard) and it brought up this:

java.lang.RuntimeException: Unrecognized item '2015-09-24 04:00:00 Etc/GMT'

I get the same thing on mine. Now I tried making a new one and that one does work properly but I don't want to make him recreate all his widgets if he doesn't have to. Any ideas?
