On a board without hardware clock this software real time clock can be

used. The initial time may be provided via the environment variable
|
|
'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.
