I work for a hospital system, and have SEVERAL Vertical Summit systems installed at various locations around town, and I was surprised to find that MOST of them are not keeping the correct time, and it is usually that the Vertical system is 8-12 minutes ahead of actual time. Is there SOME way to sync the system time to actual time ( an internal clock), or maybe some setting where I can at LEAST slow the clock down? most of the systems have been installed from 1 year to over 4 years, and the time is not consistent on any of them.
