Clock Stops Running When System Not In Use

Hello all,

So since I last posted I've been able to check our customer's router settings (I couldn't find anything in the control panel that would indicate it was messing with the time) and had them disconnect their security cameras for several days. I also had them change the power outlet the station was plugged into. None of these helped as their clock still went out of sync.

One thing I have noticed is that it seems to go out of sync on Fridays or Saturdays. If I re-sync the time on or before Thursday, the clock will be out of sync on Friday morning. If I fix it on Friday, it will be out of sync on Saturday morning. I haven't been able to try it on the weekends because I don't work on the weekends. So if I adjust the clock on Monday morning it seems to remain okay until Friday morning.

I'm pretty much at wit's end here and not sure what else could possibly be causing this

Referring back to LayBack Bears post #8 regarding employees. This is a long shot, but.. Who works on Friday and Saturday that doesn't work Monday through Thursday? Who operates the computer Monday through Thursday but not on Friday and Saturday? You may find it's an operator error or... something more sinister then an error. It sure is a mystery.

It will something so simple it's overlooked, Iv seen 'clock' things like the date changing at midday rather than midnight because the time says a.m. when it's p.m, are there any 'daylight saving' boxes to check?

I don't think it's an employee because they don't use the system for tracking hours worked, there isn't really a reason for one of them to mess with the clock, unless they're just doing it for giggles.

You could also check if their are any programs that are updating during the problem times.
Things like auto upload to a cloud [backups] that might change the time.
Also auto updating any programs.
These types of things should not be able to change the time on the computer but I'm running out of ideas.

Yeah, right now I've pretty much gone full circle and cycled back to pestering the POS software developer about this. They were the first ones I asked but they denied any culpability, but with everyone's help here I think we've pretty much eliminated anything else.

Maybe put you own admin password on all the computers so no one can fiddle with the settings.

Any chance this is one of those systems that restaurants use so you can pay at the table? If so, alarm systems and security cameras do a lot of wireless communication. Also any Bluetooth items would bear looking at. Wife had a Bluetooth mouse and a wireless thermometer played hell with the cursor in Excel. Took a while to find that one.
