This seem to start about a couple weeks ago, where the date on the Local Web Interface is one day behind. The Date/Time is correct on the EYEZ-ON Portal and the alerts Date/Time Stamp are showing correctly.
Time Zone: EDT -04:00 Eastern Daylight-Saving Time)
However, some time overnight, the Date Changes, while the time is showing the current time. If I "Reboot Envisalink" on the Local Web Interface, the Date becomes current and stays that way until after 12 midnight (Not sure if the change occurs at 3:00 AM). Is this related to something that might not be program properly on the VISTA 20P? If I not mistaken, I did not have this problem when I first install the EnvisaLink 3 back in December 2012, so maybe the Day Light Saving Time has something to do with it.
This is a known bug on Vista platform. The time doesn't roll over the day at midnight. That time isn't used for anything so I guess there hasn't been any big rush to change it.
