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. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

SPDX: Convert all of our single license tags to Linux Kernel style 2018-05-07T13:34:12+00:00 Tom Rini trini@konsulko.com 2018-05-06T21:58:06+00:00 83d290c56fab2d38cd1ab4c4cc7099559c1d5046 When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
