Abstract
The present disclosure describes embodiments of apparatuses and methods related to a computing apparatus with a real time clock (RTC) coupled to a bus, where the RTC does not have a backup power source to maintain time and date of the RTC. The computing apparatus may have firmware coupled to the bus, and the firmware may contain boot logic with network time protocol (NTP) logic. The computing apparatus may have persistent memory coupled to the bus with configuration parameters. The computing apparatus may have a controller coupled to the bus, where the controller is to retrieve the configuration parameters from the persistent memory and processes the boot logic with the NTP logic using the configuration parameters to transmit an NTP request over the bus and receives a coordinated universal time (UTC) over the bus and stores the UTC in the RTC.
