By default, KStars can sync the telescope's time and location settings to that of KStars. This is an important step before you can properly control your telescope. However, some users, especially those who frequently change locations require syncing the PC time and location settings to those of the telescope, especially since many modern telescopes are equipped with GPS receivers.
Bug 147743 was opened to address this issue. I recently committed a change to KDE svn repository to add this feature to KStars. Now users can select the source of the time and location settings!
