Change the POS Terminal’s Time Date
Also, go to the back office and go to Setup – Hardware Devices. Then double-click on “Terminal #01” and make sure the checkbox for “Allow Time Set” is checked on ALL terminal hardware profiles (ex. Terminal #02, Terminal #03, etc). If any were NOT checked, be sure to check them and click OK / Done. Then go to each POS terminal whose profile you changed and perform a terminate / relaunch.
