It seems like I hunt for this info every six months. Sometimes I just wait 6 months until the time is right again.
Setting the System Date and Time To set the system time, enter [âœ±]  followed by the Master Code. Press . The keypad will now accept 10 consecutive digits: â€¢Enter the Time in Hours and Minutes using the 24 Hour format (00:00 to 23:59). â€¢Enter the Date in Months, Days and Years (MM DD YY). NOTE: If you have an LCD keypad, your installer may have programmed your system to display the time and date while the keypad is idle. If this is the case, you may have to press the [#] key to clear the date and time before entering an access code to arm the system, or before performing any other keypad function.
