We're running v14 network version.
All along, the z-outs have printed out with a date range of whatever time the z-out was done the previous day to whatever time it's being done today.
However, our server started printing out the z-outs with BOTH times being only the time that today's z-out is being done. It's continued to do it that way every day since.
Other than the date, though, there's no apparent effect - i.e. all the items sold seem to be recorded.
Is this something I should be concerned about?
