MIC-5332 is Advantech ATCA blade, it has RTC synchronization to make sure blade boot up with synced time.
Please refer to FAQ for detail in ATCA RTC sync mechanism.
Because of Errata sheet LPC1768 (Our IPMC Chip) , the RTC is not reliable. Means settings on IPMC based is not reliable either.
Means RTC time sync set to 0x02 is NOT allowed or system time cannot be guarantee.
