With current u-boot/master, with the same test command you provided, I got:

=> date && sleep 4 && date
Date: 2018-09-06 (Thursday)    Time:  6:47:28
Date: 2018-09-06 (Thursday)    Time:  6:47:32
=> date && sleep 4 && date
Date: 2018-09-06 (Thursday)    Time:  6:47:41
Date: 2018-09-06 (Thursday)    Time:  6:47:45
=> date && sleep 4 && date
Date: 2018-09-06 (Thursday)    Time:  6:47:47
Date: 2018-09-06 (Thursday)    Time:  6:47:51

It seems there is no issue.

QEMU was invoked like this: qemu-system-i386 -nographic -bios u-boot.rom
