If the screen blinked likely there was enough outage to cause the EZSrve to reboot. You can test the success of the SET TIMEZONE click by unplugging the EZSrve for 20/30 seconds. The correct date/time should be in effect after plugging it back in assuming the EZSrve has access to the internet to get the correct date/time for specified time zone. The EZSrve will boot up automatically when power is restored but you will have to login again.
