'rtc_emul_epoch' as a decimal string indicating seconds since
1970-01-01. If the environment variable is missing, the build time is
used to initialize the RTC. The time can be adjusted manually via the
'date' command or the 'sntp' command can be used to update the RTC
with the time from a network time server. See CONFIG_CMD_SNTP and
CONFIG_BOOTP_NTPSERVER. The RTC time is advanced according to CPU
ticks.
