# RTC Control Command

The user can set the time and date using the RTCR and RTCW commands. The write command requires a password (“PIC” by default). Ensure that the format used when typing the command is exactly the same as shown in the example below.

    ; Read the RTC
    RTCR
    Present RTC is (yy-mm-dd w hh:mm:ss):
    22-11-17 4 09:59:02

    ; Set the RTC
    RTCW[PIC](22-11-17 04 10:23:40)
    Set RTC is ok !

    ; Read the RTC again
    RTCR
    Present RTC is (yy-mm-dd w hh:mm:ss):
    22-11-17 4 10:23:42

Note:

- "w" corresponds to the current day in the current week. The RTC peripheral supports a range from 1 to 7. The coding of the number (which is day 1 of the week) is user-defined as it has no effect on the date-time computation.
- Depending on the Demo Meter Application version, the temporary variables storing the demand and energy accumulated are erased each time the Time Of Use (TOUW command) or RTC (RTCW command) are programmed
