hRTC time values (adresses hRTCseconds/hRTCminutes etc.) are put back to 0 on console start

GetClock < StartClock < Init < Reset
         < _InitTime < InitTime < SetTimeOfDay < InitClock
                                < .SetClock < RestartClock (RTC overflow, RIP because 16383 days ?)
         < UpdateTime < .SetClock < RestartClock

StartRTC < StartClock < Init < Reset
