From 87e9963d5acaa41f3c54c1dee9159c775352f86a Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Thu, 22 Oct 2020 23:52:14 +0200 Subject: rtc: provide an emulated RTC On a board without hardware clock this software real time clock can be used. The build time is used to initialize the RTC. So you will have to adjust the time either manually using the 'date' command or use the 'sntp' 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.
