can UEFI use external RTC? #118

the reason is time and date in windows are always reset when booting. I think if UEFI can read external RTC like ds3231. I don't need to configure time and date in Windows

The Pi does not come with a built-in RTC.

Would be nice to support external ones, but only as opt-in (same UEFI build needs to support regular Pi as well)

Use an ntp client in the mean time
