I did some searching for an alternative and found CleanStatus. Its stable so far, and adds dozens of features on top of removing just the time. Can remove/add any single feature from the status bar, such as just the battery or just the percentage symbol between the battery level and battery, or the whole thing...and more.
Back on Topic, Mindi, if you can edit the files to remove the slider, can the same be done to make themes compatible with 4.3.1? Thanks.
