7.1.3 Set date and time
COMMANDS SET DATE AND TIME
The date and time can be entered on the front panel keypad. The time setting is based on the 24-hour clock. The complete
date, as a minimum, must be entered to allow execution of this command. The new time and date take effect when the
ENTER key is pressed.
The clock also can be synchronized to the local computer time among several UR devices. Use the Synchronize Devices
entry in the Online Window area of the EnerVista software. (Click the button at the top of the window that opens.)
When the relay is synchronizing to an external time source such as PTP, IRIG-B, or SNTP, the manually entered time or the
manually synchronized time is over-written.
The timescale of the entered time is local time, including daylight savings time where and when applicable.
